VerwendenSodium selenide is used in paper and pulp industry, for kraft process followed by photographic industry to prevent developer solutions. It finds application as a bleaching agent in textile industry, sulfur dyes and detergents. It is also used to impart color to glass, glazes and enamels. Further, it acts as a decolorizer of glass due to neutralization of greenish tint produced by iron (ferrous) compounds. It plays an important role to prepare organoselenium compounds by reacting with alkyl halides.
