Li Lithium ( LI6.94) 3 Li Characters Lithium is a soft, silver-white metal with symbol Li and atomic number 3. It belongs to the alkali metal group of chemical elements. Under standard conditions it is the lightest metal and the least dense solid element. Like all alkali metals, lithium is highly reactive and flammable. For this reason, it is typically stored in mineral oil. When cut open, lithium exhibits a metallic luster, but contact with moist air corrodes the surface quickly to a dull silvery gray, then black tarnish. Because of its high reactivity, lithium never occurs freely in nature, and instead, only appears in compounds, which are usually ionic. Lithium occurs in a number of pegmatitic minerals, but due to its solubility as an ion is present in ocean water and is commonly obtained from brines and clays. On a commercial scale, lithium is isolated electrolytically from a mixture of lithium chloride and potassium chloride. 2 ( Aladdin® ) Inorganic compounds www.aladdin-e.com period 2 • Lithium Item货号 No. 品名 Product Name 规格 Specification CASCAS 包装Pkg.

Because any beryllium synthesized in stars is short-lived, it is a relatively rare element in both the universe and in the crust of the Earth. It is a divalent element which occurs naturally only in combination with other elements in minerals. Notable gemstones which contain beryllium include beryl (aquamarine, emerald) and chrysoberyl. As a free element it is a steel-gray, strong, lightweight and brittle alkaline earth metal. Beryllium increases hardness and resistance to corrosion when alloyed to aluminium, cobalt, copper (notably beryllium copper), iron and nickel. In structural applications, high flexural rigidity, thermal stability, thermal conductivity and low density (1.85 times that of water) make beryllium a quality aerospace material for high- speed aircraft, missiles, space vehicles and communication satellites . Because of its low density and atomic mass, beryllium is relatively transparent to X-rays and other forms of ionizing radiation; therefore, it is the most common window material for X-ray equipment and in particle physics experiments .The high thermal conductivities of beryllium and beryllium oxide have led to their use in heat transport and heat sinking applications. period 2 • Beryllium Item No. Product Name Specification CAS Pkg.

It is a soft, silvery-white, highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na. The free metal does not occur in nature, but instead must be prepared from its compounds; it was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Sodium is the sixth most abundant element in the Earth's crust, and exists in numerous minerals such as feldspars, sodalite and rock salt. Many salts of sodium are highly water-soluble, and their sodium has been leached by the action of water so that chloride and sodium are the most common dissolved elements by weight in the Earth's bodies of oceanic water.

Nanostructuring of tungsten composites is expected to dramatically improve the materials’ properties and enhancing the performance in present applications but also enabling totally new possibilities. Nanostructured WC-Co materials have been the focus of researchers and engineers for over two decades. New fabrication methods have been developed. But, the fabrication of true nanograined WC-Co composites is still a challenge. Nanostructured tungsten-based materials for applications as plasma facing materials in fusion reactors have attracted a growing interest. This Thesis summarizes work on the development of chemical methods for the fabrication of two different types of nanostructured tungsten-based materials; WC-Co composites mainly for cutting tools applications and W-ODS materials with yttria particles, intended as plasma facing materials in fusion reactors. The approach has been to prepare powders in two steps: a) synthesis of uniform powder precursors containing ions of tungsten and cobalt or yttrium by precipitation from aqueous solutions and b) processing of the precursors into WC- or W-based nano-composite powders.

    NIOSH Manual of Analytical Methods (NMAM), 5th Edition Sampling and Analysis of Soluble Metal Compounds by Kevin Ashley, Ph.D., NIOSH and Richard Fairfax, CIH, OSHA [Much of this chapter was adapted from Fairfax and Blotzer 1994; and Ashley 2001.] 1 Introduction SM-2 2 Soluble and insoluble metal compounds SM-2 3 Health effects SM-4 4 Sampling considerations SM-5 5 Analytical considerations SM-5 6 ISO procedure for soluble metals and metalloids SM-7 7 Summary SM-10 8 References SM-11 9 Appendix - Solubilities of selected metals and metal compounds SM-14 DEPARTMENT OF HEALTH AND HUMAN SERVICES Centers for Disease Control and Prevention National Institute for Occupational Safety and Health Sampling and Analysis of Soluble Metal Compounds 1 Introduction Workplace exposure standards have been established for several soluble metals and metalloids to take into account the increased bioavailability of some metal compounds. Exposure standards for soluble compounds can be up to 500 times lower than the exposure standards for less soluble compounds for the same metal. However, there is often confusion among chemists, industrial hygienists, and laboratories over what is meant by “soluble” when the metal species, extraction fluid, or solubility conditions are not specified in the exposure standard nor in the supporting exposure standard documentation [Fairfax and Blotzer 1994]. In addition, the metals and metal compounds may interact chemically or physically with the sampling media or with each other [Ashley 2001]. Such complications can affect the stability and speciation of the metals and their compounds, and must be addressed in order to obtain meaningful results.
