Molecular formula: Zn
Molecular weight: 65.38
Appearance: Light gray powder
Properties: Insoluble in water, soluble in acids and bases, slowly soluble in acetic acid and ammonia water. With strong reducibility, it releases hydrogen gas through acid-base interactions. Caking when getting wet.
Usage: Zinc powder is a main raw material for manufacturing paints, coatings, and chemical products, as well as a reducing agent for organic synthesis. In addition, it is widely used in the metallurgical industry, battery industry, as well as pesticide, feed, dye and pharmaceutical industries.
