Selenium Metallicum Supplier and Exporter

The biggest use of selenium is as an additive to glass. Some selenium compounds decolourise glass, while others give a deep red color. Selenium can also be used to reduce the transmission of sunlight in architectural glass, giving it a bronze tint. Buy metallicum online, which is used to make pigments for ceramics, paint, and plastics. Selenium Metallicum has both a photovoltaic action (converts light to electricity) and a photoconductive action (electrical resistance decreases with increased illumination). It is therefore useful in photocells, solar cells, and photocopiers. It can also convert AC electricity to DC electricity, so is extensively used in rectifiers. Selenium is toxic to the scalp fungus that causes dandruff so it is used in some anti-dandruff shampoos. Selenium is also used as an additive to make stainless steel. Selenium metallicum uses a very rare element. Scientists estimate its abundance at about 0.05 to 0.09 parts per million on earth. Selenium ranks among the 25 least common elements available in the Earth’s crust. It is widely distributed throughout the crust. There is no ore from which selenium can easily be mined with profit. Instead, we get ca6nm material properties as a by-product of mining other metals. Due to its semiconductor abilities, it has been used for almost a century to rectify circuits. Additionally, it is photoconductive and photovoltaic which means the presence of light increases the production/conduction of electricity. For this reason, it is often used in electronics such as photocells and solar cells. In small concentrations, selenium produces a pink color which is used to decolorize glass by offsetting the green/yellow tint that is often created by iron impurities. Selenium is a non-metallic chemical element and it occurs naturally in the environment in a number of inorganic forms, including selenide, selenate, and selenite, but these minerals, as mentioned before, are rare.

The grey (metallic) form of selenium is formed when other varieties are heated to 200C; this has a melting point of 220C and a relative density of 4.80. Selenium is widely distributed, mainly as the selenides of heavy metals, but only has an abundance of 0.05 ppm in the earth’s crust. The metal burns in the air and is unaffected by water. It is soluble in alkalis and concentrated nitric acid.
