Product Description
Chemical properties
Borax is a colorless crystal, weathered in the air, dehydrated into anhydrous sodium tetraborate when heated to 400-500°C, and melted into glass at 878°C. Because the melt contains acidic oxide B2O3, it can dissolve metal oxides. This property can be used to remove oxides on the metal surface when welding metals. Many metal oxides often show characteristic colors after being dissolved in molten borax, such as cobalt metaborate Co(BO2)2 is blue, nickel metaborate Ni (BO2)2 is brown, chromium metaborate Cr(BO2)3 is emerald green, etc.
Physical properties
Borax is the sodium salt of boric acid, the general name of sodium tetraborate, which is a boron-containing mineral. According to the amount of crystal water, it can be divided into three types: decahydrate borax, pentahydrate borax and anhydrous borax.
(1) The chemical name of borax decahydrate is sodium tetraborate decahydrate, the molecular formula is Na2B4O7·10H2O, and the molecular weight is 381.37. It is colorless translucent crystal or white crystalline powder, odorless, salty, density 1.73g/cm3, melting point 75℃. In dry air, it can slowly lose water and become weathered. When heated to 300-400°C, all crystal water will be lost and transformed into anhydrous sodium tetraborate Na2B4O7. Soluble in water and glycerin, insoluble in alcohol. 878 ° C melting into a glass-like substance.
(2) The chemical name of borax pentahydrate is sodium tetraborate pentahydrate, the molecular formula is Na2B4O7·5H2O, the molecular weight is 291.29, it is a white crystalline powder, the density is 1.815g/cm3, when it is heated to 122°C, it loses crystal water and turns into anhydrous Sodium tetraborate.
(3) The chemical name of anhydrous borax is sodium tetraborate, the molecular formula is Na2B4O7, the molecular weight is 201.22, it is white crystal or glass body, and there are two forms of α and β: α orthorhombic crystal, melting point 742.5 ℃, density 2.28g/cm3, β Orthorhombic crystal, melting point 664°C, density 2.75g/cm3, strong hygroscopicity, soluble in water, slowly soluble in methanol, and can form a solution with a concentration of 13-16%. In addition to heat resistance, water resistance and acid resistance, borax also has strong dissolving power. Borax turns white and expands after heating, and becomes a transparent glass ball, in which metal oxides can be dissolved to restore the original color of the metal. This is the famous borax ball reaction. Borax can be used in the manufacture of capacitors, in various glass products, and in the ceramic industry as a glaze. It is used as antifreeze and anticoagulant in mining and metallurgical industry, and as electrolyte additive and welding agent in nonferrous metal industry. In addition, it is used in the manufacture of preservatives, herbicides, soil fungicides and borides.
