Chemical property:
Insoluble in water, soluble in acids and bases, slowly soluble in acetic acids and ammonia hydroxide, with strong reducing action, releasing hydrogen after action with acid-bases Become lump after being affected with damp.
Purpose:
Zinc powders are main raw materials to manufacture paints, coatings and chemical products, such as rongalite, sodium zincates and zinc oxides and reducing agents of organic synthesis. In addition, they are widely applied to metallurgical industry, battery industry, pesticide, fodder, fuel and pharmacy industry.
