China OEM Carbon Activated - Manufacturers Supply Industry Borax Anhydrous – EASFUN Detail:
Anhydrous borax/sodium tetraborate appearance is white crystalline or colorless vitreous crystal. The melting point of alpha orthorhombic crystal is 742.5 ℃, and the density is 2.28; The melting point of beta orthorhombic crystal is 742.5℃, and the density is 2.28. It has strong hygroscopicity and can soluble in water and glycerol. It is slowly dissolved in methanol to form a solution with a concentration of 13-16%. the aqueous solution is weak alkaline, insoluble in alcohol. Anhydrous borax is the product obtained when borax is heated to 350-450 ℃. When placed in air, it can be hygroscopically changed into borax decahydrate or borax pentahydrate.
