Barium Selenite (CAS 13718-59-7) is a specialized inorganic compound supplied as a Technical Grade white powder, used as a refining agent in high-end glass manufacturing to decolorize glass by neutralizing the green color imparted by iron contaminants. The material is critical for the decolorization of glass , where it effectively neutralizes the green color imparted by iron contaminants. Its high density and low solubility contribute to stable performance in glass melt furnaces. Commercially, it is preferred in the production of optical glass and decorative crystals for its ability to produce clear, colorless results. It maintains a stable chemical structure even under extreme industrial heating conditions.
