English name: sodium sulphate (sodium sulphate anhydrous)

Molecular formula: Na2SO4

Molecular weight: 142.04

 

Physical character:

Achromatic colour, hygroscopic property white pellet crystal or powder. Easy to dissolve in water , dissolve in glycerin , not dissolve in alcohol , aqueous liquor is neuter. Higher purity , granule exiguous thing is called sodium sulphate. Sodium sulfate may form seven water thing or ten water thing , seven water thing (Na2SO4.7H2O) is white askew square crystal. When heat to 24.4 centigrade become anhydrous thing. Sodium sulfate and carbon are deoxidized become sodium sulfide during the pyroreaction.

 

Use:

Be used as fill agent at sapide. The chemical product manufacture such as be used for the sodium sulfide , sodium silicate , be used to make sulfate paper pulp at paper making industry, instead of soda ash at glass industry, be used as fill agent at fuel industry. At dye printing industry be used for assistant dye agent, at medicine industry be used for catabatic lax reagent and barium salt toxicosis antidote etc. Besides, also be used at produce synthetic fibre, process hides , coloured metallurgy , enamel , soap etc.
