CAS 1304-28-5 Barium Oxide as Chemical Raw Materials

CAS 1304-28-5 Barium Oxide as Chemical Raw Materials

Product Overview

Barium oxide has a molecular formula of BaO and a molecular weight of 153.33. It is a colorless cubic crystal. Soluble in acid, insoluble in acetone and ammonia. The reaction with water or steam reacts intensely with an exothermic reaction to form barium hydroxide. It is easy to absorb water and carbon dioxide in the air to form barium carbonate. poisonous! Used in glass and ceramic industries, also used in beet sugar refining, raw materials for the manufacture of barium peroxide and barium salts, as dehydrating agents and high-efficiency desiccants. Used as a desiccant, also used in the formulation of optical glass and electronics, instrumentation, metallurgical industry. A desiccant for gas, which produces barium peroxide and barium salts. A getter and superconducting material for preparing black and white, color picture tubes and various electric vacuum tubes.
