Understanding the EU supply-demand, trading and applications of these metals is important for taking good decisions and ensure their supply according to the future needs and therefore the development of Europe. For each metal, a first part has been devoted to applications in the EU and how far the equilibrium is reached. In a second part, the market trends of the different uses and the substitutability opportunities have been assessed based on different assumptions, in order to estimate the future needs during the 10 coming years. Eventually, a set of solutions is proposed for each metal, from exploiting new primary or secondary resources to an increase of recycling rates. Approval Date By 2016-12-01 09:06:04 Pr.

The major sources of tungsten include primary mining and recycling. China is the major producer of primary tungsten with estimated 85% of world mine production. Europe has mines of tungsten in its territory but the mine production still doesn’t meet the demand of the European industries. Cemented carbides, steel and alloys, mill products, and chemicals and specialists are the main applications of tungsten. In the report the tungsten productions from mines and scraps recycling, major suppliers and the demand of tungsten in Europe are presented. In addition, the future demand of tungsten in Europe is discussed based on the collected data. CURRENT SUPPLY AND DEMAND MINE PRODUCTION (TUNGSTEN CONCENTRATE) According to the most recent US Geological Survey (USGS) report [1] on the metal, world tungsten production in 2013 was 81,400 tonnes, and in 2015 it reached 87,000 tons, an increase over 2014’s 86,800 tonnes. The European countries which currently produce tungsten from mines include Austria, Spain, Portugal and the UK. They ranked 7 to 10th in the list of the world’s top tungsten‐producing countries in 2015. Austria, produced 870 tonnes of tungsten in 2015, the same amount it produced in 2014 mainly from the Mittersill mine. Spain produced 730 tonnes and 800 tonnes of tungsten in 2015 and 2014, respectively. Portugal’s tungsten output was 630 tonnes in 2015 and 671 tonnes in 2014. The Panasqueira mine is Portugal’s largest tungsten‐ producing mine. Finally, the UK made it onto the board with 600 tonnes of production. Wolf Minerals opened its Hemerdon tungsten mine in Devon in the fall of 2015. The total mine productions of tungsten in 2014 and 2015 were 2,341 and 2,830 tonnes in Europe. In 2013 2.52% of global tungsten mine production (81,400 t) was from Austria, Portugal and Spain [1]. According to 2013 data from the International Tungsten Industry Association (ITIA), the recycling rate (RR) was 50% in Europe and the United States in contrast to 30% in Japan although the global recycling rate of tungsten was 10‐25% in 2011. It was reported [5] that since 2008 the tungsten consumption in Europe was about 10,000 tonnes. Because the recycling rate was 50% the tungsten production from recycling was about 5,000 tonnes in recent years. MSP‐REFRAM DX.X [Title] Rev.0| 2 The total production in the year of 2013, 2014 and 2015 can be estimated by combining the mine production and the production from recycling which are shown in Table 1. Table 1: Production of tungsten from mining and end‐of‐life scraps in EU (unit: tonnes) Mine End‐of‐life scrap Total 2013 2051 5000 7051 2014 2341 5000 7341 2015 2830 5000 7830 TUNGSTEN CARBIDE Tungsten carbide is the largest application of tungsten. In 2005, 14,600 tonnes of tungsten carbide was produced in Europe according to the report [3] and the global production of tungsten carbide was 39,000 tonnes.

Hamel Laboratoire de Génie Chimique, Département Procédés Electrochimiques et Matériaux, CNRS UMR 5503, Université Paul-Sabatier, 118 route de Narbonne, 31062 Toulouse Cedex 04, France (Received 12 February 2003; accepted 18 April 2003) Abstract This article deals with the different modes of preparation of alloys or intermetallic compounds using the electrodeposition in molten salts, more particularly molten alkali fluorides. The interest in this process is to obtain new materials for high technology, particularly the compounds of reactive components such as actinides, rare earth and refractory metals. Two ways of preparation are considered: (i) electrocoating of the more reactive metal on a cathode made of the noble one and reaction between the two metals in contact, and (ii) electrocoating on an inert cathode of the intermetallic compound by coreduction of the ions of each elements. The kinetic is controlled by the reaction at the electrolyte interface. A wide bibliographic survey on the preparation of various compounds (intermetallic compounds, borides, carbides…) is given and a special attention is paid to the own experience of the authors in the preparation of these compounds and interpreta- tion of their results. Keywords: Electrosynthesis, alloys, intermetallic, compounds, molten salts, alkali fluorides, co-reduction, reactive electrodeposition 1.

  • Interactions of Lanthanides and Liquid Alkali Metals for “Liquid-Like” Lanthanide Transport in U-Zr Fuel
    Interactions of Lanthanides and Liquid Alkali Metals for “Liquid-Like” Lanthanide Transport in U-Zr Fuel THESIS Presented in Partial Fulfillment of the Requirements for the Degree Master of Science in the Graduate School of The Ohio State University By Jeremy Payton Isler Graduate Program in Nuclear Engineering The Ohio State University 2017 Master's Examination Committee: Dr. Jinsuo Zhang, Advisor Dr. Marat Khafizov, Co-Advisor Copyrighted by Jeremy Payton Isler 2017 Abstract One of the major limitations in achieving increased burnup in metallic U-Zr nuclear fuel is Fuel-Cladding Chemical Interaction (FCCI). The migration of the fission product lanthanides from within the fuel to the peripheral is one of the major contributors to FCCI. A “liquid-like” transport mechanism proposes the lanthanide transport is aided by liquid cesium and liquid sodium in the pores of the fuel and at the fuel peripheral. The purpose of this thesis was to provide additional experimental evidence towards this proposed mechanism. This thesis investigated the interaction between the lanthanides and cesium and sodium, with a focus on the solubility of the lanthanides in these liquid alkali metals. First, a prediction of the solubility was calculated using the Miedema model. This prediction was then compared to the inversion crucible solubility experiment performed in this thesis. The solubility experiment studied the temperature and liquid-composition dependence of the lanthanides in liquid sodium, cesium and sodium-cesium mixtures. In addition, the solubility in mixtures shows the various alkali metals concentration effect on the solubility. With the results of differential scanning calorimetry (DSC) experiments, updated phase diagrams for sodium-neodymium and cesium-neodymium were obtained from the experimental data in this thesis.

    Making BaZrS3 chalcogenide perovskite thin films by molecular beam epitaxy Ida Sadeghi1,2, Kevin Ye1, Michael Xu1, James M. LeBeau1, R. Jaramillo1† 1. Department of Materials Science and Engineering, Massachusetts Institute of Technology, Cambridge, MA, USA 2. Department of Electrical and Computer Engineering, University of Waterloo, Waterloo, ON, CA † [email protected] Abstract We demonstrate the making of BaZrS3 thin films by molecular beam epitaxy (MBE). BaZrS3 forms in the orthorhombic distorted-perovskite structure with corner-sharing ZrS6 octahedra. The single-step MBE process results in films smooth on the atomic scale, with near-perfect BaZrS3 stoichiometry and an atomically-sharp interface with the LaAlO3 substrate. The films grow epitaxially via two, competing growth modes: buffered epitaxy, with a self-assembled interface layer that relieves the epitaxial strain, and direct epitaxy, with rotated-cube-on-cube growth that accommodates the large lattice constant mismatch between the oxide and the sulfide perovskites. This work sets the stage for developing chalcogenide perovskites as a family of semiconductor alloys with properties that can be tuned with strain and composition in high-quality epitaxial thin films, as has been long-established for other systems including Si-Ge, III-Vs, and II-Vs. The methods demonstrated here also represent a revival of gas-source chalcogenide MBE. Introduction Sulfides and selenides in the perovskite and related crystal structures – chalcogenide perovskites, for brevity – may be the next family

Tantalum has a density of 16.69 g/cm3, a melting point of 3017 oC and a resistivity of 13.1 µOhm cm. It is hard and has a Brinell hardness of 440 – 3430 MPa. Tantalum forms compounds in oxidation states -III to +V. Most commonly encountered are oxides of Ta(V), which includes all minerals. Its standard electrode potential in respect to Ta+3 is -0.6V. Tantalum is highly corrosion-resistant. At temperatures below 150 °C tantalum is almost completely immune to attack by the normally aggressive aqua regia. It can be dissolved with hydrofluoric acid or acidic solutions containing the fluoride ion and sulfur trioxide, as well as with a solution of potassium hydroxide. Its abundance has been estimated to be ~ 2 parts per million (ppm) of the Earth’s crust. Plating Solutions The electrodeposition of reactive metals such as aluminum (Al), magnesium (Mg) and tantalum (Ta) from aqueous solutions is impossible causing hydrogen evolution to occur at the cathode, due to the narrow potential window in aqueous solutions. Electrodeposition from fused salt electrolytes is a general plating technique for the majority of electronegative refractory metals (Ta, Nb, Mo, W, Zr, Hf, Ti, V et al) [1]. It is the most practical method, which can yield thick, high purity, coherent and dense coatings.

The as mples were subsequently exposed to air at an elevated temperature. In tests at 800°C, the phosphided samples resisted air oxidation markedly compared to the pure untreated samples. The hospp hided cases were only a few microns thick yet oxidation resistance of all these samples extended for several hours. Phosphided samples with 90° edges did not resist oxidation at the edges as well as rounded edge samples.

  • What Are Refractory Metals?
    What are Refractory Metals? Refractory metals are different. As a group they provide a number of unique characteristics – such as resistance to high heat, corrosion and wear – making them useful in a multitude of applications. The next time you climb into your automobile take note that you are surrounded by components which are made of refractory metals or have been cut or formed by them. Your car’s electrical or electronic systems may also make use of the metals’ electric and heat-conducting qualities. On the other hand, refractory metals were used in the tools which helped to drill the well which produces the gasoline in your tank. Piping of refractory metal alloys helped process it. And your oil may contain a refractory metal compound to increase its lubricating ability. The paradox of refractory metals is that, despite their wide and constantly growing list of applications, many people – sometimes even engineers, working with one of the metals – do not fully understand how and where each is mined, how it is processed, how it is formed, or even understand the full extent of the diversity of refractory metals’ applications. Five Metals with Unique Characteristic Tungsten W Molybdenum Mo Niobium Nb Tantalum Ta Rhenium Re Excellent strength at high temperatures. Even when heated to 1000oC (1832oF) tungsten rocket nose cones still have twice the tensile strength iron has at room temperature. Very high melting point (2468oC/4474oF to 3410oC/6170oF): High melting points of tungsten, tantalum and molybdenum make them useful in processing molten metals and minerals such as glass making. 1 Excellent wear and abrasion Exceptional resistance to resistance: Refractory metals, often corrosion.

Initiation of the supporting activities is underway. These include a scoping assessment and design of the fuel reprocessing and separation systems and the transmutation of actinides using fast reactors and accelerator- driven systems. Our initial assessment indicates the Z-Pinch could be an attractive option for burning actinides (Pu, Np, Am, Cm) and/or minor actinides (Am, Cm) produced by the fission fuel reprocessing plants. A Z-transmuter would need a 200 MJ target injected every 10 seconds to transmute the actinides and deliver a net electric power of 1 GW.
