Theboron ores in different countries have different characteristics, which de termine diverse production methods of boric acid. Among all these production methods the acid method is the principle one. Boric acid is widely used in many fields such as glass industry, ceramics, metallurgy, mechanics, electron, medicine, agriculture, national defense, modern science andtechnology etc. Thede veloping direction of boron industry is intensivism, largescaleandfine. Fine chemical boron productswith high added value, new materials containing boron and anhydrous or highpurity boric acid for special pur pose (medicine, reagent, photograph and nuclear reactor etc.) will develop extensively.
