mercury powder is a white powder made by grinding up mercury (mercury metal) or mercury compounds. It is used in medicine as a cathartic and diuretic. It also has antifungal properties and is used in ointments for fungal skin diseases.Inorganic mercury has a variety of uses and is important for...
Adding tin to the copper metal improves its ability to withstand stresses from machining and handling. In addition to its workability, it also increases its strength and ductility to make it suitable for bearing applications. For example, high leaded tin bronzes are used in rolling mills for the support of...
is lead ii fluoride soluble in waterThe solubility of a compound depends on the forces that interact between the solvent molecules and the solute molecules. The stronger these interactions are, the higher the solubility. The solubility of a compound also increases with the temperature of the solution.A compound is soluble...
Bismuth is one of the post-transition metals (the pnictogens), with chemical properties that are between those of its lighter group 15 sibling antimony and heavier parent lead. It is a brittle, silvery-white, crystalline metal that, with surface oxidation, displays a rosy tinge. It is the most naturally diamagnetic metal and...
Article SummaryThe mineral hgcro4 (hexahydrocomancheite) is a new hg-bearing mineral that forms when 10-4 M HgO and 10-4 M chromic acid are combined under hydrothermal conditions. The crystal structure of a-hgcro4 has been re-determined and consists of distorted [HgO7] pentagonal bipyramids, containing tetrahedral chromate anions. The monohydrate b-hgcro4 adopts the...
zirconium hydride powder is a dark gray to black metallic powder used in many applications including as a moderator in nuclear reactors, and in the fabrication of metal foams. zirconium hydride powder is also used in the production of zirconium and zirconium alloy products using powder metallurgy processes. The powder...
The melting point of a metal is its temperature where it begins to transition from a solid state into a liquid. It is a key property that is used to determine the suitability of metals for certain applications and projects. When alloys are used, their melting points vary and depend...
Lead was one of the first metals known to man and has been used throughout history for a variety of structural, ornamental and other purposes. Probably the oldest known lead artifact is a figure made about 3000 BC. All civilizations, from the ancient Egyptians, Assyrians and Babylonians through to modern...
boron selenide is a nonmetal chalcogenide with a boron-rich structure. It is a bridging compound between carbon and silicon-germanium (CSG). The chemical formula of the boron selenide is B6X where X represents either S or Se. The crystal structure of boron selenide was determined experimentally by powder X-ray diffraction and...
invar tube is a nickel-iron alloy that is noted for its uniquely low coefficient of thermal expansion. It contains 36% nickel and has a rate of thermal expansion approximately one-tenth that of carbon steel at temperatures up to 400degF (204degC).Invar is used in applications requiring high dimensional stability for large,...
