Selenide Powder

Selenium is a non-metallic element with the chemical symbol Se, which is in group VI A (element 34) of the fourth period of the periodic table of the chemical elements. Selenium is with the CAS no. 7782-49-2, the melting poing of selenium is 221℃, the boiling point of selenium is 684.9℃. Selenium is not soluble in water. The density of selenium is 4.81 g/cm3. Selenium has the appearance of a grey solid with a metallic lustre. The atomic weight of selenium is 78.96.
Selenide means that hydrogen selenide dissolved in water can precipitate many heavy metal ions into particles. Selenium and metals in oxidation state +1 can generate two kinds of selenides, namely, positive selenide (m2se) and acid selenide. Selenium is one of the essential trace elements of the human body and organisms. It can regulate the absorption and consumption of vitamins A, C, E, and K. It cooperates with vitamin E to protect cell membranes, and participates in the catalytic reactions of various enzymes in the body. It is an important component of glutathione peroxidase (GSH-Px) and iodothyronine deiodinase (ID).

Applications of Selenide Powder
Selenide Powder are used in electronics, glass, metallurgy, chemical industry, health care, agriculture and other fields.
Selenium has photosensitivity and semiconductor characteristics, and is often used in the electronics industry to manufacture photovoltaic cells, photoreceptors, laser devices, infrared controllers, photocells, photoresistors, optical instruments, photometers, rectifiers, etc. The application of selenium in the electronics industry accounts for about 30% of the total demand.
Selenium and selenide powders are important semiconductor materials with excellent optoelectronic properties.
