Na2SO4 FAQ

What is the properties of Anhydrous Sodium Sulfate?
Anhydrous sodium sulfate is in the form of hygroscopic white powder and has no odor.
Formula of anhydrous sodium sulphate is Na2SO4
Na2SO4 is soluble in water but insoluble in ethanol.
Anhydrous sodium sulfate's boiling point is 1100ºC, and the melting point is 880-888ºC.
Anhydrous sodium sulphate is stable under ordinary conditions, but at high temperature it is reduced to sodium sulfide.
Specific gravity of anhydrous sodium sulphate is 2.66-2.75.
Anhydrous sodium sulfate density is 1.464 /g cm3.
Anhydrous sodium sulfate assumes a monoclinic structure at 100ºC and above 250ºC it assumes a hexagonal structure.
It does not react with oxidizing agents at normal temperature.
What is the facts of Sodium Sulphate Anhydrous
Anhydrous sodium sulphate is found in nature in the form of a mineral, known as, thenardite.
Anhydrous sodium sulfate is the sodium salt of sulfuric acid.
When it grows in the pores of stones, anhydrous sodium sulphate can exert pressure on the rocks and make the structures crack.
Anhydrous sodium sulphate tends to attract iron compounds and organic compounds.
The production of this compound is 6 million tons, which makes it one of the world's majority commodity chemicals.
However it is also one of the world's most damaging salts in structure conservation!

What Is Anhydrous Sodium Sulfate’s usage?
Anhydrous sodium sulphate is mainly used in laundry detergents. In fact, in 2001, the use of anhydrous sodium sulphate was 1.6 million, out of which 80% was used for home laundry detergents, in Europe!
Another major use of sodium sulfate in U.S.A, is for manufacturing wood pulp, in the Kraft process.
Na2SO4 is also used for manufacturing textiles. As it helps in reducing negative charges on fibers, helping the dyes to penetrate evenly and thus helping in 'leveling'.
Anhydrous sodium sulphate is used in the glass industry. Not for producing glass, but for removing air bubbles from the molten glass. It also prevents scum formation of the glass as it fluxes the glass.
The other uses of anhydrous sodium sulphate include starch manufacture, in carpet freshmen, in frosting windows, and also as an additive to cattle feed. Anhydrous sodium sulphate is also used in the laboratory, as an inert drying agent for organic solutions. In addition to all theses uses, sodium sulphate is used in electronic and water treatment industry.
One of the latest usage of anhydrous sodium sulphate has been found. It has been discovered that anhydrous sodium can dissolve fine electroplated micrometer gold, which is found in electronic products such as connectors, switches and pins.
Store up and transportation
Should store at the ventilated , dry storehouse. In summer or high temperature easy to unfreeze and coagulate become big block, should protection against the tide , guard against rain. Pay attention to keep the packing entireness, avoidance get in touch with food , coal, cement etc.. When catch fire, use water and any fire extinguisher to save.
