Detailed Product Description: | Metal selenium, selenium rods, with selenium, selenium powder, selenium Article Long-term supply of imports of the metal selenium, 3 # Se ingots, rods selenium, selenium belt, 3 # selenium powder, selenium bar, symbol: Se; Color: Silver; density: 2.99, melting point: 1541; Boiling Point: 2830; mainly used to produce transistor and the photoelectric tube, etc.; and for coloring glass; Selenium is one of scattered metal. Frequently Asked whether the amorphous and crystalline selenium allotrope of two. Amorphous body was red and black, melting point 40-50 ℃ (softening), density 4.25-4.28 g / cm 3, of crisp, crystal takes the shape of dark red gray, melting point 170-217 ℃, density 4.46-4.70 g / cm 3. The nature of selenium and sulfur similar, but stronger metallic than sulfur. The most significant feature of selenium in the light than in darkness there is thousands of times its conductivity increases. Selenium can be dissolved in concentrated nitric acid oxidation and alkali at room temperature without oxidation, as oxidation of selenium when heated combustion. The use of selenium in selenium can be used in the electronics industry photoelectric cells, solar cell, fax, television and radio are also used selenium. In addition, selenium in glass, paint and metallurgical industry applications. Selenium can make glass coloring or bleaching, high-quality signal with a glass lens containing 2% selenium, selenium flat glass used for solar panels and laser heat transfer window filters. Metallurgy, Se carbon steel, stainless steel and copper alloy with good processing performance, high-speed cutting, machining parts surface finish; selenium and other elements of the alloy used to manufacture low-voltage rectifiers, photovoltaic cells, thermoelectric materials. Selenium compounds in the form to be used as oxidants in organic synthesis, catalyst, can be applied in the oil industry. Selenium can trace additives for animal feed. Selenium can be added to enhance its wear resistance of rubber. Selenium and selenium compounds by adding lubricating grease can be used for ultra-high lubrication. Selenium detoxification of heavy metal poisoning. Sodium selenate treat "Keshan disease", price below the market price, quality and acceptance by national standards.
