Sodium sulphate anhydrous(99% )/SSA Good quality Competitive price Large stock Delivery in time Sodium sulphate anhydrous

Molecular formula: Na2SO4CAS NO.: 7757-82-61.Product characteristics and uses It is white fine particles or powder, and has a characteristic of crystallization hygroscopic, soluble in water, and water solution shows neutral. Soluble in glycerin, not soluble in alcohol. When exposed to the air, it will absorb one molecules water. High purity and the fine grain without water called sodium sulphate anhydrous. Sodium sulfate can form seven water compound and ten water compound. The seven water compound (Na2SO4 · 7 H2O) is white trapezius crystal, when heated up to 24.4 °C , it will turned into anhydrous compound. When sodium reacted with carbon, it will be reduced to zinc sulfide colloid. It could be used as filling agent for synthetic detergent; used for the manufacturing of chemical products such as sodium sulfide, ultramarine, sodium silicate, etc; used for the production of sulfate pulp in the paper industry; could be used instead of soda ash in the glass industry; used as filling agent for dyestuff industry; used as  dyeing assistant in printing and dyeing industry; used as used delay evacuant and antidote barium salt poisoning in the pharmaceutical industry, etc; In addition  it could be used in the manufacture of synthetic fiber, leather making , non-ferrous metals, enamels ,soap, etc. 2.Data for reference  Item  GB/T6009-2003 I group First quality Normal quality Medium and high quality High quality Standard  data Tested data Tested data Tested data Na2SO4 % ≥99.0 99.15 99.30 99.65 Water insoluble matter % ≤0.05 0.02 0.03 0.01 Ca and Mg (Mg) % ≤0.15 0.02 0.02 0.02 Chloride (Cl)% ≤0.35 0.19 0.20 0.05 Fe% ≤0.002  0.001  0.001  0.001 Moisture % ≤0.20 0.02 0.02 0.02 Whiteness% ≥80 88 85 83 PH Value Not required 4.5~6 or 8~12 6~8 or 8~12 6~8 or 8~12
