White crystal containing two crystal water. Lose two crystal water at exceeding 113ºC bitter taste noxious, soluble in water, slightly soluble in alcohol, insoluble in ether.
Produce barium salt materials, cotton reducing printing dyeing, leather industry, pharmacies, rodenticide and disinfestation, photographic chemical, heat treatment agent, water softener, boiler compound, paper making, dyes pigment, rayon extinction.
It is the raw material for making barium salt.It can be used as insecticide to prevent and control many kinds of plant pests.Brine and boiler water used for refining electrolytic caustic soda.It's also used to make pigments.The textile and leather industries are used as mordants and artificial silks.Machinery industry used for quenching and metal processing.
Colorless monoclinic crystal.The density of 3.097 g/cm3.Boiling point 35.7 ℃.Soluble in water.Slightly soluble in hydrochloric acid, nitric acid, extremely soluble in alcohol.Lose two crystallization water when heated to 113 ℃.Poisonous!Barium sulfide, which is reduced by barite and coal, is prepared by adding hydrochloric acid into the mixture after wet grinding.It can also be made by reducing the melt barium sulfide with barite and coal powder, after soaking with calcium chloride solution, and then treating with carbon dioxide the immersion solution containing barium sulfide and calcium chloride.Used in the manufacture of other barium salts, barium geodesic paper, artificial silk polishing agents, high temperature quenching agents for metal heat treatment, neutral heating agents, fillers for organic pigments, insecticides, etc
