Samarium Metal Purified 99.9%

Samarium metal is silvery white metal crystal, which is available in powder, foil, rod, sheet, granule and sputtering target. It is hard as iron and own good ductility, but poor electric conductivity. Sm metal is relatively stable in dry air, however in moisture air, the surface oxidize and forms oxide layer. Samarium powder is soluble in water, however insoluble in water, which tends to self ignite. Sm metal easily compound with non-metallic element, for example samarium nitridesamarium hydridesamarium boridesamarium sulfide. There are two production methods, reduction method and distillation method. The distilled samarium piece is dendritic with higher purity than reduced one.

Sebacoyl Chloride

Sebacoyl chloride is a di-acyl chloride. It is corrosive; like all acyl chlorides, it hydrolyzes in water rapidly, evolving hydrogen chloride. Sebacoyl chloride can be reacted with hexamethylenediamine, to give the polymer, nylon-6,10.

Selenium

Selenium is a nonmetal, chemically related to sulfur and tellurium, and rarely occurs in its elemental state in nature. It conducts electricity better in the light than in the dark, and is used in photocells. It is found in economic quantities in sulfide ores such as pyrite, partially replacing the sulfur in the ore matrix. The chief commercial uses for selenium today are in glass making and in chemicals and pigments. Uses in electronics, once important, have been supplanted by silicon semiconductor devices. It is used widely in vitamin preparations and other dietary supplements, in small doses. Some livestock feeds are fortified with selenium as well. It is used in the toning of photographic prints. Selenium is a catalyst in many chemical reactions and is widely used in various industrial and laboratory syntheses, especially organoselenium chemistry. It is also widely used in structure determination of proteins and nucleic acids by X-ray crystallography.

Selenium Dioxide

Selenium dioxide is one of the most frequently encountered compounds of selenium. It is an important reagent in organic synthesis. It imparts a red colour to glass: it is used in small quantities to counteract the blue colour due to cobalt impurities and so to create colourless glass. In larger quantities, it gives a deep ruby red colour. It is the active ingredient in some cold-blueing solutions. It is also used as a toner in photographic developing.
