Brief Introduction
Sodium sulfide is mainly used as raw material for raw leather unhairing agent, pulp cooking agent, sulfide dye, dye intermediate reducing agent, fabric dyeing mordant and ore flotation agent, as well as viscose fiber desulfurizer and raw material for production of sodium hydrosulfide and sodium polysulfide. In the dyestuff industry, sodium sulfide is used to produce sulfur dyes, which is the raw material of sulfur blue and sulfur blue. In the printing and dyeing industry, sodium sulfide is used as a dyeing aid to dissolve sulfide dyes. In the leather industry, sodium sulfide is used to hydrolyze the raw hide to remove hair, and to prepare sodium polysulfide to speed up the soaking of dry skin to help soften. In the paper industry, sodium sulfide is used as a cooking agent for paper. In the textile industry, sodium sulfide is used for denitrification of man-made fibers, reduction of nitrocellulose and mordant for cotton dyeing. In the pharmaceutical industry, sodium sulfide is used to produce pyrolytic drugs such as phenacetin. In addition, sodium sulfide is also used to prepare sodium thiosulfate, sodium hydrosulfide, sodium polysulfide, etc.

Brief Introduction
Copper oxide is an inorganic substance with the chemical formula Cuo. It is a black oxide of copper, slightly amphoteric and slightly hygroscopic. It is insoluble in water and soluble in acid. It can decompose oxygen under high temperature. Hydrogen or carbon monoxide can be reduced to copper at high temperature. Copper oxide is heated in air and releases oxygen at about 1050 ℃ to reduce to cuprous oxide. If in the gas stream of hydrogen or carbon monoxide, it is easy to be reduced to metal copper even below 250 ℃. Although copper oxide is insoluble in water, it can be dissolved in aqueous alkali metal hydroxide solution.
It is used as colorant in glass, enamel and ceramic industry, anti Zou agent in paint and polishing agent for optical glass. It is used in the manufacture of dyes, organic catalyst supports and copper compounds. It is also used in rayon manufacturing industry and as a desulfurizer for grease. It is used as the raw material for manufacturing other copper salts and artificial gemstones.

Brief Introduction
Ammonium hydroxide can be used in the production of nitric acid and nitrogen fertilizer, as well as the production of dyes, pharmaceuticals, plastics and circulating refrigerants. For example, the gallium arsenide V-groove pattern substrate can be prepared with ammonium hydroxide etching solution. The obtained gallium arsenide V-groove pattern substrate is relatively smooth and flat, and there are few defects caused by corrosion. The ammonium hydroxide etching solution used is anisotropic etching solution with moderate corrosion rate.
