Product Name:Sodium tetraborate decahydrate
English Name:Sodium tetraborate decahydrate
CAS No.:1303-96-4
Aliases:Borax, Borax decahydrate, Sodium borate decahydrate, Disodium tetraborate decahydrate
Molecular Formula:Na2B4O7·10H2O
Physical Properties:Colorless translucent crystal or white crystalline powder, odorless, saline taste. Freely soluble in water and glycerol, insoluble in ethanol. Aqueous solution is alkaline. Loses all water of crystallization at 350–400 °C, forming a colorless glassy mass upon melting.
Uses:Used as a flux and raw material in glass, ceramic glaze and enamel industries; used as a component of buffer solutions and a raw material for boric acid in analytical chemistry; also widely used in detergents, disinfectants, preservatives and metal welding fluxes.
Technical Specifications:
Purity (as Na2B4O7·10H2O) ≥ 98%
Appearance: colorless translucent crystal or white crystalline powder
Water insoluble matter ≤ 0.05%
Iron (Fe) content ≤ 0.002%
Loss on drying (water of crystallization) complies with relevant national standards
