Barium carbonate, chemical formula BaCO3, molecular weight 197.35. Hexagonal fine crystals or white powder. It is hardly soluble in water, with a density of 4.43 g/cm2 and a melting point of 1740°C (8820 kPa-90 atmospheres). Decomposes at 1450°C and emits carbon dioxide. Slightly soluble in water containing carbon dioxide, but also soluble in ammonium chloride or ammonium nitrate solution to form a complex, dissolved in hydrochloric acid and nitric acid to release carbon dioxide. poisonous. Used in electronics, instrumentation, and metallurgical industries. Preparation of fireworks, signal bombs, ceramic coatings, and auxiliary materials for optical glass. Barium carbonate is also widely used in ceramic tiles, etc.
