描述
1 CAS No.: 10043-35-3 MF: H3BO3
2 Quality standard: Boric Acid(H2BO3)GB/T538-2006
3 Uses:
Heat resistant glass, glass fibres, porcelain enamals, boron chemicals, metallurgy, flame retardant in sellulosic insulation, mattress batting, fungus control and textile products.
4 Properties:
Odorless white powder or scalelike crystal with smooth felt, Soluble in water, ethanol, glycerol, ether and essential oil. Aqueous solution is weak acidic. It will gradually lose water if heated, and will produce boron anhydrous at 300° C.
5 Package: 50kg/PP woven bag with PE liner inside.
6 Storage:
Store in a cool, dry, well ventilated place out of direct sunlight. Store away from metals, reducing agents, alkali carbonates and hydroxides.
