Zinc Oxide is white or light gray powder, non-toxic and odorless. Its specific gravity is 5.47, melting point 1975ºC. It is soluble in acid and alkali, insoluble in water and alcohol.
Zinc Oxide properties:
1. white powder or hexagonal crystal, odourlessness, relative density: 5.606g/cm3, stable nature under normal temperature. 2. insoluble in water and alcohol, soluble in acid, alkali and ammonium hydroxide. 3. Zinc oxide is a kind of white pigment, also called zinc white. When heated, it will turn to yellow, but after cooling down, it still turn back to white.
Zinc oxide Application
1, Used as white dyestuff and used in printing & dyeing , paper, match and medicine industry. 2, Used in rubber industry as vulcanization activator, reinforecement agent and coloring agent of natural rubber, synthetic rubber and latex. 3, Used in the processing of zinc chrome yellow, zinc acetate, zinc carbonate, zinc chloride, etc. 4, Used for making electron laser materials, flurescent powder, forage additives, catalysts, magnetic materials.
