Sodium sulphide (sodium sulfide) 25kg, wholesale is an inorganic substance, an oxygen-free salt, sensitive to environmental humidity, and slowly oxidizing in air. It dissolves well in water, but is not stable in the form of a solution, it quickly oxidizes. May be airborne as an aerosol. Toxic in contact with the skin and mucous membranes of humans and animals. Its content in the air is normalized by MPC values. On contact with acids, it reacts with the release of hydrogen sulfide.

Sodium sulfide is classified as a highly hazardous substance (class 2), as well as explosive and flammable. In this regard, it is necessary to strictly adhere to the requirements for safe transportation, storage and use, set out in GOST 596-89.

The chemical formula is Na2S.

Where is it applied?

In the chemical industry for the production of sulfur dyes and cellulose, as a strong reducing agent in a number of chemical processes, it is used in the form of a 15-25% alloy solution - a semi-finished product for the production of sodium sulfide, as well as a reagent and an indispensable reagent in chemical analysis;

In metallurgy, sodium sulfide has found application in the smelting of certain non-ferrous metals;

For the enrichment of lead-zinc, copper, molybdenum and some other ores of the mining industry.
