Introduction of precipitated barium sulfate
Precipitated barium sulfate, also known as industrial barium sulfate or barium carbonate. It is made by artificial processing, and unlike barium, the sink is almost free of impurities. It is slightly soluble in water and insoluble in acids. It is not poisonous, but it can cause poisoning if it contains soluble barium. In the industry of precipitated barium sulfate mainly through reaction with sulfuric acid, barium sulfate, barium chloride and sulfate or sodium sulfate and sodium sulfate barium sulfide generation. Because the stability of precipitated barium sulfate by its specific indicators be used as filling material in different fields of medicine, high-grade paint and ink, plastic, rubber, glass, ceramics etc., people usually according to different applications and divided into coating grade precipitated barium sulfate, precipitated barium plastic grade sulfuric acid and so on, the price relative to the weight of barium high.
Its chemical properties are very stable, insoluble in water, and acid, alkali, non-toxic, non-magnetic, and can absorb X- rays and gamma rays. In nature, barium sulfate, also known as barite, is a natural mineral, usually in the shape of a bifurcated crystal, mainly determined by the variety and number of impurities contained in it, and pure barite is colorless and transparent. Barite has no direct harm to the human body and can be contacted directly. Industrial classification, barium sulfate is more common, is divided into the following categories: 1. Ba, also known as barite powder or natural barium powder.
In textbooks, the chemical formula for barium sulfate in physics and chemistry is BaSO4, which is generally a white orthorhombic, colorless and odorless, with a density of 4.499 and a melting point of up to 1580 DEG C.
