Sodium Sulphate Anhydrous
CAS 7757-82-6 · Na2SO4 · HS 2833.11
Sodium sulphate anhydrous (CAS 7757-82-6) is a neutral inorganic salt produced as a by-product of rayon and chromate manufacture or mined from natural thenardite and glauberite deposits. Its highest-volume use is in kraft pulping make-up chemical, followed by glass melting as a fining agent, powder detergent filler, textile dyeing levelling agent and, historically, in the sulphate process for TiO2. Buyers compare Na2SO4 assay, water-insoluble matter, iron content, whiteness and moisture, and select between natural and by-product origins depending on trace-metal sensitivity.
