production method
Method One: Carbonization In the yttrium sulfide solution (see Preparation of sulphide), carbon dioxide gas is carbonized to obtain a barium carbonate slurry which is desulfurized and washed, vacuum filtered, dried at 300° C., and pulverized to obtain a barium carbonate finished product. The reaction formula is as follows: BaS+CO2+H2O→BaCO3↓+H2S↑ metathesis method The metathesis reaction of yttrium sulphide and Ammonium Carbonate, followed by washing, filtration, drying, etc., to obtain the barium carbonate finished product. The reaction formula is as follows: BaS+ (N
H4)2CO3→BaCO3↓+(N
H4) 2S poisonous stone conversion method reacts toxic heavy stone ore with ammonium salt to form soluble barium salt, and ammonium carbonate is used for recycling. The soluble barium salt is added with ammonium carbonate to precipitate refined barium carbonate, which is filtered and dried to obtain barium carbonate. Finished product. The resulting mother liquor is recycled for recycling.
use
It is mainly used in the manufacture of optical glass, picture tube glass, and neodymium magnetic materials and capacitors, as well as steel carburizing and metal surface treatment. It is a raw material for the manufacture of other barium salts and ceramics, enamels, paints, coatings, rubbers, and welding rods. Also used as a water purifying agent and rodenticide, oxidation catalyst.

1> Cosmetic Raw Materials: Cosmetics is a variety of raw materials through a reasonable deployment of processing from the compound mixture. Cosmetics with a wide range of raw materials, different performance. According to the raw material properties and uses of cosmetics, can be divided into matrix materials and auxiliary raw materials in two categories. The former is a class of cosmetics in the main raw materials, cosmetics in the possession of a large proportion of the cosmetics play a major role in the role of the material. The latter is the formation of cosmetics, stability or to give color, smell and other characteristics of the role of these substances in the cosmetic formula is not used, but it is extremely important. Cosmetics are natural, synthetic or extracted from the role of different substances as raw materials, by heating, mixing and emulsification and other production processes processed from the chemical mixture.
2> Active Pharmaceutical Ingredients(API): API refers to the raw materials in the production of various types of preparations, which is the active ingredient in powder,crystal and paste for medicine use through chemical synthesis,plant extract, and preparations of biotechnology institute.It is one substance or mixture during the medicine making period uut it can not be taken directly by patients.
3> Fragrance And Spices: Spice is a substance that can be scented by smelling or scented by taste, and is the raw material for the preparation of the fragrance. Spices are an important part of fine chemicals, it is composed of natural spices, synthetic spices and single fragrance.
4> Organic Raw Material: Intermediates are also known as organic intermediates. The use of coal tar or petroleum products as raw materials to produce dyes, pesticides, pharmaceuticals, resins, additives, and other intermediates.
5> Chemicals Used In Paints: Paint, the traditional Chinese name is paint. So-called coating is coated on the surface of the object that be protected or be adornment, and with the continuous film coating to form strong adhesion, usually in resin, or oil, or emulsion is given priority to, add or not add pigment, filler, add the corresponding additives, organic solvents or water preparation of viscous liquid.
