Sodium Sulphide 101: A Beginner's Guide to Properties, Uses & Safety (2026)

Understanding Sodium Sulphide: Chemical Properties and Industrial Significance

Sodium sulphide (Na₂S) is an inorganic compound with a distinctive rotten egg odor, primarily recognized for its reducing properties in industrial applications. As a leading Sodium Sulphide manufacturer, Shandong JunTeng Chemical produces high-purity Na₂S flakes (60-62% content) with superior reactivity compared to standard market offerings (typically 58-60%).

The compound's unique ability to donate electrons makes it indispensable in:

• Leather processing (removes hair 40% faster than enzymatic methods)
• Pulp bleaching (reduces chemical oxygen demand by 25-30%)
• Metal precipitation (removes 99.9% heavy metals from wastewater)
