as the major chemical raw material of the production of caustic soda, soda ash, widely used in alkali industry. As a semiconductor silicon doping source, it can be used for preparation of high purity boron and organic boron compound. Trona is mainly used for making soda ash, caustic soda, soda, and other products. Soda ash is an important industrial raw material, widely used in glass, chemicals, light industry, textile, dyeing, metallurgy, petroleum processing, pharmaceuticals, food and so on. Caustic soda is mainly used for rayon, paper, dyes, soap, plastics, pharmaceuticals, agricultural chemicals and so on. Baking soda is mainly used in food, plastics, rubber, pharmaceutical, printing and dyeing, tanning, soaking seeds and other areas.As a dopant materials of semiconductor, catalyst, intermediate and brominated agent of organic synthesis, It is a raw material for producing high purity boron and other organic boron compound.Used in organic synthesis and preparation for high purity boron.As catalyst, intermediates and Brominating agents for organic synthesis, raw materials for manufacturing high purity boron and other organic boron compound.
