Description

Selenium is obtained in either a silvery metallic form (grey Se) or a red amorphous powder, which is less stable. Selenium burns in air, is unaffected by water, but dissolves in concentrated HNO3 and alkalis. It is used in photoelectric cells, photocopiers, solar cells and semiconductors.
