What is Sodium Sulfate Sodium sulfate (Na 2 SO 4) is the sodium salt of sulfuric acid.. Anhydrous sulfate is a white crystalline solid also known as the mineral thenardite, while the decahydrate Na 2 SO 4.10H 2 O has been known as Glauber’s salt or mirabilis.. Na 2 SO 4.7H 2 O is transformed to mirabilite when it is cooled. Mirabilite is the natural mineral form of the decahydrate.
May 22, 2017· Sodium sulfate is one of the most used chemical compounds in many fields since the 17 th century when it is discovered. You must be glad Johann Glauber discovered it. The first reason is because by using this sal mirabilis as Glauber named it, we can make a powdered detergent.We can wipe out the dirty things or stains on our clothes to make our clothes cleaner.
Sodium dodecyl sulfate (SDS), an anionic surfactant, is a common ingredient of cosmetic and personal care products. SDS is "readily biodegradable" with low toxicity and "is of no concern with respect to human health". Up to 1 g of SDS/kg is the maximum safe dose for children. Alkyl sulfates, including SDS, are microbicidal against HIV types 1
Sodium sulfate has proven to be an effective additive for enhancing the reduction and metal aggregation during the carbothermic reduction of Ni laterite ore. In this study, the effect of Na₂SO₄ on the non-isothermal reduction kinetics of Ni laterite ore with solid C was investigated.
Solid ore containing mirabilite, with fresh water dissolution, get a solution of sodium sulfate. Chemically treated, gravity sedimentation or filtration to remove insoluble substances, carry out vacuum evaporation in the crystallizer. After crystals and solution separation, then adopt air drying method to dry, the client can get sodium sulfate.
A process for the preparation of anhydrous sodium from a thenardite ore containing sodium sulfate comprising the steps of: crushing the thenardite ore; lixiviating the crushed ore in a first lixiviation step with water or with an exhausted solution from a succeeding step, at a temperature between about 28° C. and 40° C., obtaining a suspension comprising a sodium sulfate saturated solution
At present, the company owns glauberite ore resources, which are availe for 400 years. There are 1,500 employees, and all operators are professional technical personnel. Owning 3 sodium sulfate production lines with the most advanced quintuple effect external heated forced circulation vacuum production technology, the company can produce 1
