What are the properties of zinc sulfide?

What is Zinc Sulfide?
Zinc sulfide is an inorganic compound with the chemical formula ZnS. It is white or yellowish powder, which turns dark when exposed to light. It is stable in dry air, and gradually oxidizes to zinc sulfate when it is stored in wet air for a long time or contains moisture.
Use of Zinc Sulfide powder
1. Rubber industry: In the vulcanization process of lead-zinc mine equipment rubber, zinc oxide can improve the physical properties of vulcanized rubber, enhance the activity of the accelerator, shorten vulcanization time, and improve the wear resistance and tensile mechanical properties of rubber. Secondly, it can be used as a reinforcing agent and coloring agent for rubber, as well as a vulcanizing agent for chloroprene rubber and a compounding agent for increasing thermal conductivity.
2. Paint industry: It mainly uses its coloring power, hiding power, anti-corrosion, luminous and other functions. Commonly used to produce white paint and enamel. Slightly alkaline, zinc oxide can react with trace-free fatty acids to form zinc soap, which makes the paint film flexible and firm, and prevents metal oxidation.
3. In the printing and dyeing industry: zinc oxide is used as a resist agent; In the chemical industry, zinc oxide is used as a catalyst. In addition, it is also used as a raw material for the production of opal glass and zinc white oil paints and watercolor pigments, as well as cosmetics and zinc salts.
Physical and chemical properties of Zinc Sulfide powder
Physical features:
White or yellowish powder. Burning in H2S gas will transform into crystals. α is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700. The β variant is a colorless cubic crystal with a density of 4.102g/cm3, and it is converted to α at 1020. It exists in sphalerite. Insoluble in water and soluble in acid. See the sun darken.
Chemical property:
Turn it into zinc sulfate in humid air for a long time. Generally, hydrogen sulfide reacts with zinc salt solution. If a small amount of Cu, Mn, and Ag is added to ZnS crystal as an activator, it will emit different colors of fluorescence after illumination. Used as analytical reagent, coating, paint making, white and opaque glass, filling rubber and plastic, and preparing fluorescent powder.
Price of Zinc Sulfide powder
Zinc Sulfide powder particle size and purity will affect the product's price, and the purchase volume can also affect the cost of Zinc Sulfide powder. A large amount of large amount will be lower. The price of Zinc Sulfide powder can be found on our company's official website.
