Introduction to the physical and chemical properties of barium carbonate
Barium carbonate, chemical formula BaCO3, molecular weight 197.35. Hexagonal fine crystals or white powder. Insoluble in water, density 4.43 g/cm3, melting point 1740°C (8820 kPa-90 atmosphere). It decomposes at 1450℃ and releases carbon dioxide. Slightly soluble in water containing carbon dioxide, also soluble in ammonium chloride or ammonium nitrate solution to form a complex, soluble in hydrochloric acid and nitric acid to release carbon dioxide. poisonous. Used in electronics, instrumentation, and metallurgical industries. Preparation of fireworks, signal flares, ceramic coatings, and auxiliary materials for optical glass. Also used as rodenticide, water clarifier and filler.
Introduction to barium carbonate and lithium carbonate storage and transportation conditions
Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The packaging is sealed. They should be stored separately from acids and food chemicals, and avoid mixed storage. Suitable materials should be available in the storage area to contain spills.
Introduction to the uses of barium carbonate
Auxiliary materials for ceramic coatings and optical glasses are used in the manufacture of electronic ceramics, PTC thermistors, capacitors and other electronic components. Analysis of iron hexahydroxypentacobalt dicarbonate in calcium, magnesium, manganese and zinc. Determination and determination of halogens in organic compounds. It is used to make barium salts, pigments, fireworks, rodenticide pottery, and as fillers and water clarifiers. Used in catalysts. It produces electronic ceramics and purified water, and produces pigments, coatings or other barium salts for the production of optical glass, barium magnetic materials, etc. It is an important chemical raw material for the production of picture tube glass shells, magnetic materials and advanced optical glass. It can be used to treat excess sulfate radicals in the chromium plating electrolyte. It can also be used in the white passivation solution of the zinc plating layer and can also be used to treat wastewater.
Introduction to the dangers of barium carbonate
Barium carbonate is a barium salt and is highly toxic. Barium carbonate will accumulate on bones and cause the proliferation of bone marrow leukocyte tissue, leading to chronic poisoning. The LD50 of barium carbonate is about 418mg/kg. For patients with acute barium carbonate poisoning, measures such as gastric lavage, enema, and emetics are usually taken to eliminate barium carbonate from the body. At the same time, you can also take potassium sulfate to react with barium carbonate, which can turn toxic barium into insoluble barium sulfate and precipitate, reducing the toxicity. Potassium sulfate is used because barium carbonate poisoning may cause hypokalemia.
