Borax is preparing boron-containing compound of the basic raw material, borax, almost all containing boron can be prepared by the borax. They metallurgy, steel, machinery, military, tools, paper, tubes, chemical and textile sectors have an important and wide range of uses. [Identifying characteristics] short columnar crystal form, low hardness, soluble in water, sweet and slightly salty. Easy to dehydration in the air, borax effect, color becomes cloudy, the surface crack and heroin massive hull form. When the expansion of the fire, the fusible into glass sphere. Chinese name: borax. Chemical formula: Na2B4O7 · 10H2O. Molecular Weight: 381.37CAS. Melting point: about 880 ℃. Boiling point: 1575 ℃. Water solubility: soluble in water. Density; 1.69 ~ 1.72 Appearance: White fine crystals. Colorless translucent crystals or white crystalline powder. Odorless, borax use, salty taste. Molecular structure of losing the whole borax [1] section 1.73.380 ℃ when the proportion of crystal water. Soluble in water and glycerine, slightly soluble in alcohol. Aqueous solution is alkaline. Borax in the air can slow weathering. Melting into a colorless glass-like substance. Borax has bactericidal action, oral harmful to people.
