Nature:

Yellow or red flakes, strong moisture absorption, soluble in water, and water

solution is strongly alkaline reaction. Sodium sulphide will cause burns when

is touched with the skin and hair. The method of solution in the air will slowly

oxygen. Sodium thiosulfate, sodium sulfite, sodium sulphide and sodium

polysulfide, because sodium thiosulfate’s generating speed is faster,

its major product is sodium thiosulfate. Sodium sulphide is deliquesced in

theair and carbonated so that it is metamorphic, and constantly release

hydrogen sulfide gas. The industrial sodium sulphide includes impurities, so

its color is red. Specific gravity and boiling point are influenced by impurities.

Function and Usage:

Sodium sulphide is used to produce vulcanization dye,sulphur cyan,

sulphur blue, dye intermediates reductance, and other nonferrous

metallurgy industry used for ore flotation agents. Sodium sulphide can

also make the depilatory cream in the leather industry. It is cooking

agent in the paper industry.Meanwhile, sodium sulphide is also used to

produce Sodium thiosulfate, sodium sulfite andsodium polysulfide.
