Selenium Powder

Product Description

Selenium Powder (Se) is a nonmetallic element known for its semiconducting, photoconductive, and catalytic properties. It exists as a red to gray crystalline powder and is widely used in electronics, glass manufacturing, metallurgy, and analytical chemistry.
In laboratories, Selenium serves as an analytical reagent, nutritional trace element standard, and precursor for inorganic and organoselenium compounds. Its unique chemical and electrical properties make it valuable in chemical synthesis, photovoltaic cells, and photocopying processes.
