Property: white or colorless, smooth crystals or powder; soluble in water. Alcohol and glycerin. 6. Usage: 1) raw materials of glass, enamel, porcelain, pharmaceutical industry. 2) glass and glass fiber for the production of optical glass, acid glass, organic glass and borosilicate glass and other advanced glass fiber, glass can improve the heat resistance and transparency, improve the mechanical strength, shorten the melting time. B2o3 in the manufacture of glass and glass flux and networks play a dual role in the formation of the body. For example, in glass fiber production by helping to reduce the melting temperature of drawing. in general, b2o3 can reduce the viscosity, controlled thermal expansion, to prevent loss of transparency, improve chemical stability, improved resistance to mechanical shock and thermal shock resistance. Requirements of low sodium content in the glass production of sodium borate and boric acid is often (such as borax pentahydrate or anhydrous borax) mixed with sodium to regulate the b glass ratio. Borosilicate glass which is very important, because boron oxide alumina in the case of sodium as well to help dissolve the performance. 3) for the production of boric acid ointment, disinfectant, astringent, antiseptic and so on.
