Brief Introduction to Sodium Sulfate


Sodium Sulfate (Na2SO4) is one of the most important minerals in the chemicals industry. Natural sodium deposits are formed by a long geologic process of the erosion of igneous rocks, the transportation of sodium from these rocks and chemical reactions. First, the sodium is released from igneous rocks when they weather and break down. In the right situation, the sodium is carried by water in rivers, streams and as runoff and collects in basins. Then, when it comes in contact with sulfur, it precipitates out as sodium sulfate. The sulfur can come from the weathering of the mineral pyrite (iron sulfide), from volcanic sources, or from gypsum beds (gypsum is calcium sulfate).The mineral thenardite is natural sodium sulfate. Thenardite was named after the French chemist Louis J. Thenard. It is soluble in water and has a salty taste like the mineral halite.
Sodium sulfate is chemically very stable - it does not decompose, even if heated, and it does not react with oxidizing or reducing agents at normal temperatures. At high temperatures, it can be reduced to sodium sulfide. It is a neutral salt, with a pH of 7 when dissolved in water, because it is derived from a strong acid (sulfuric acid) and a strong base (sodium hydroxide).
Sodium Sulfate, Technical Grade, Anhydrous is used in paper pulping to enhance the strength of the finished product, lower production costs, and reduce downtime. Glass manufacturers use Sodium Sulfate, Technical Grade, Calcined to improve the quality of the refined glass melt.Sodium Sulfite reacts with formaldehyde to form nonvolatile products. It has been suggested as a scavenger for free formaldehyde in urea-formaldehyde resins used for foam insulation, plywood, and particle board. Sodium Sulfate has also been used to neutralize leather tanning solutions, thereby increasing the chrome penetration and chrome concentration in leathers.
