They are near the north border of a stock of Silver Plume granite, to which they are genetically related. Numerous lenticular schist masses in the granite suggest proximity to the roof. The cerite rock containing about 75 per cent of cerite occurs as irregular lenses,one- fourth of an inch to 15 inches wide, in narrow aplite-pegmatite zones along the borders of small schist areas. Narrow veinlets of black allanite border the cerite rock and minute grains of uraninite (pitchblende) and pyrite are localiy present. Microscopic examination of the cerite rock shows it to be finely intergrown with * Published by permission of the Director, Geological Survey, United States Depart- ment of the Interior, the Colorado Geological Survey Board, and the Colorado Metal Mining Fund. 381 E.

  • Exemption for the Use of Cadmium in Portable Batteries and Accumulators
    Exemption for the use of cadmium in portable batteries and accumulators intended for the use in cordless power tools in the context of the Batteries Directive 2006/66/EC Final Report (revised) 26 January 2010 Consortium ESWI Expert TeamBIPRO, to S upportUmweltbundesamt Waste Implementation BiPRO Beratungsgesellschaft für integrierte Problemlösungen ENV.G.4/FRA/2007/0066 iii European Commission ESWI Final Report - Replacement of Cadmium Batteries in Cordless Power Tools ENV.G.4/FRA/2007/0066 iv Executive Summary Background The Batteries Directive 2006/66/EC (repealing Directive 91/157/EEC) entered into force on 26 September 20061. The Directive sets out rules applicable to all batteries and accumulators that are put on the European Union market. These rules include, among others, restriction on the use of cadmium in portable batteries and accumulators (PBA) according to Article 4(1)(b) of the Directive. Portable batteries and accumulators, including those incorporated into appliances, that contain more than 0,002% of cadmium by weight shall not be placed on the market. However, according to Article 4(3) of the Directive the above requirement shall not apply to portable batteries and accumulators intended for use in: (a) emergency and alarm systems, including emergency lighting; (b) medical equipment; or (c) cordless power tools. Furthermore, based on Article 4(4) of the Directive the Commission shall review the exemption from the cadmium ban for use in cordless power tool with a view to the prohibition of cadmium in batteries and accumulators. The Commission shall submit a corresponding report to the European Parliament and to the Council by 26 September 2010, together, if appropriate, with relevant proposals.

  • THE MAJOR RARE-EARTH-ELEMENT DEPOSITS of AUSTRALIA: GEOLOGICAL SETTING, EXPLORATION, and RESOURCES Figure 1.1
    CHAPTER ONE WHAT ARE RARE- EARTH ELEMENTS? 1.1. INTRODUCTION latter two elements are classified as REE because of their similar physical and chemical properties to the The rare-earth elements (REE) are a group of seventeen lanthanides, and they are commonly associated with speciality metals that form the largest chemically these elements in many ore deposits. Chemically, coherent group in the Periodic Table of the Elements1 yttrium resembles the lanthanide metals more closely (Haxel et al., 2005). The lanthanide series of inner- than its neighbor in the periodic table, scandium, and transition metals with atomic numbers ranging from if its physical properties were plotted against atomic 57 to 71 is located on the second bottom row of the number then it would have an apparent number periodic table (Fig. 1.1). The lanthanide series of of 64.5 to 67.5, placing it between the lanthanides elements are often displayed in an expanded field at gadolinium and erbium. Some investigators who want the base of the table directly above the actinide series to emphasise the lanthanide connection of the REE of elements. In order of increasing atomic number the group, use the prefix ‘lanthanide’ (e.g., lanthanide REE: REE are: lanthanum (La), cerium (Ce), praseodymium see Chapter 2). In some classifications, the second element of the actinide series, thorium (Th: Mernagh (Pr), neodymium (Nd), promethium (Pm), samarium 1 (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), and Miezitis, 2008), is also included in the REE dysprosium (Dy), holmium (Ho), erbium (Er), thulium group, while promethium (Pm), which is a radioactive (Tm), ytterbium (Yb), and lutetium (Lu).

    NASA TN D-5301 RARE EARTH FLUORIDES AND OXIDES - AN EXPLORATORY STUDY OF THEIR USE AS SOLID LUBRICANTS AT TEMPERATURES TO 1800 ° F (1000 ° C) By Harold E. Sliney Lewis Research Center Cleveland, Ohio NATIONAL AERONAUTICS AND SPACE ADMINISTRATION For sale by the Clearinghouse for Federal Scientific and Technical Information Springfield, Virginia 22151 - CFSTI price $3.00 ABSTRACT Powdered lanthanide trifluorides such as LaF 3 and CeF3, when used as solid lubri- cants, significantly reduced the wear of Inconel 600 riders in sliding contact with Inconel 750 during lubrication experiments ia air and in argon at temperatures up to 1800 ° F (1000 ° C). Rare earth oxides were poor lubricants compared to the fluorides. Fluoride powders were good film-formers; they were smeared into adherent film on the wear track by the stresses in the zone of sliding contact. The oxides were not film-formers. It was also shown that fusion-bonded LaF 3 and CeF 3 coatings, containing CaF 2 - BaF 2 eutectic or LiF as melting point depressants, have possibilities as solid lubricant coat- ings. RARE EARTH FLUORIDES AND OXIDES - AN EXPLORATORY STUDY OF THEIR USE AS SOLID LUBRICANTS AT TEMPERATURESTO 18000F (I000° C) by HaroldE. Sliney LewisResearch Center SUMMARY Powdered lanthanide trifluorides such as LaF 3 and CeF3, when used as solid lubricants, significantly reduced the wear of Inconel 600 riders in sliding contact with Inconel 750 during variable temperature lubrication experiments in air and in argon atmospheres. At a sliding velocity of 6 feet per minute (0.03 m/sec), the friction coefficients in air were about 0.5 at room temperature, gradually decreased to 0.2 at 1000 ° F (540 ° C), and remained at that level to 1800 ° F (1000 ° C).

The crystal structure and mineral chemistry of thalénite-(Y) were analysed by electron microprobe analysis, X-ray diffraction and micro-Raman spectroscopy from a new locality in the peralkaline granite of the Golden Horn batholith, Okanogan County, Washington State, USA, in comparison with new analyses from the White Cloud pegmatite in the Pikes Peak batholith, Colorado, USA. The Golden Horn thalénite-(Y) occurs as late-stage sub-millimetre euhedral bladed transparent crystals in small miarolitic cavities in an arfvedsonite- bearing biotite granite.
