Product Introduction:

Industrial sodium sulfide is generally a mixture with different crystalline water, molecular formula Na?S·nH?O, appearing as yellow or reddish-brown lumps, flakes, and granules. It is mainly used in industries such as papermaking, dyes, mineral processing, and printing and dyeing.

The GB/T10500—2000 standard classifies industrial sodium sulfide products into three categories: Class 1 is ordinary sodium sulfide (commonly known as red alkali); Class 2 is low-iron sodium sulfide (commonly known as yellow alkali); Class 3 is high-content sodium sulfide.
