Product Definition

Disodium Sulfide (Na2S) is a yellowish, solid flake that emits a sulfurous, rotten‑egg odor. While it can exist as Na2S, its most prevalent form is the hydrated version, Na2S·9H2O. Both variants dissolve readily in water, yielding strongly alkaline solutions. Sodium sulfide is mainly produced by heating sodium sulfate with coal or hydrogen.

In its hydrated state, sodium sulfide serves a multitude of industrial functions: it facilitates dye and colour manufacture, supports metallurgy, drives chemical synthesis, aids mining operations, and plays a key role in waste management. Its capacity to treat wastewater, soil, and process sludge further underscores its significance in leather and textile industries.
