1.Chemical industry for the manufacture of sodium silicate sodium sulfide water glass and other chemical products.

2.Paper industry used in the manufacture of sulfate pulp cooking agent.

3.It is used in glass industry to replace soda ash as co-solvent.

4.It is used in textile industry to deploy vinylon spinning coagulant.

5.It is used in non-ferrous metal metallurgy, leather and so on.

6.Used in sodium sulfide, paper pulp, glass, water glass, porcelain enamel, also used as laxative and antidote of barium salt poisoning. It is a by-product of manufacturing hydrochloric acid with table salt and sulfuric acid. Chemically used in the manufacture of sodium sulfide, sodium silicate, etc.. It is used in the laboratory to wash away barium salt. It is also used in paper making, glass, printing and dyeing, synthetic fibers, leather making, etc. In the organic synthesis laboratory, sodium sulfate is used as a raw material to make NaOH. 

 In the organic synthesis laboratory, sodium sulfate is a common post-treatment drying agent.

7.mainly used as a synthetic detergent filler. In the paper industry, it is used as a cooking agent in the manufacture of sulphate pulp. In the glass industry, it is used to replace soda ash. Chemical industry used for the manufacture of sodium sulfide, sodium silicate and other chemical products of raw materials. The textile industry for the preparation of PVC spinning coagulation baths. The pharmaceutical industry is used as a laxative. Also used in non-ferrous metallurgy, leather and so on.

8.so that the hydration product calcium sulphur aluminate is generated more quickly, thus accelerating the rate of hardening of cement hydration. The amount of sodium sulfate is generally 0.5% to 2% of the cement quality, which can improve the early strength of concrete by 50% to 100%, 28%. Day strength sometimes increased, sometimes decreased, the increase in the range of about 10%, with the variety of cement, maintenance conditions and its admixture vary. Also used as a synthetic detergent filler, also used in the paper industry, glass industry, chemical industry, textile industry and pharmaceutical industry.

9.used as analytical reagents, such as dehydrating agent, digestion catalyst when nitrogen fixing, interference inhibitors in atomic absorption spectroscopy analysis. It is also used in the pharmaceutical industry.

10. used in chemical, paper and glass, dyestuff, printing and dyeing and pharmaceutical industry, in synthetic fibers, tanning, non-ferrous metallurgy, enamel and other manufacturing applications, also used in detergents and soap as an additive.

11.It can be used as buffer to stabilize plating solution in sulfate galvanizing.

Sodium sulfate has many other uses and is a common chemical reagent.
