Physical and chemical properties: white hexagonal crystal or powder. Tasteless, non-toxic, quality and delicate. The relative density of 5.606. Refractive index 2.008-2.029. Melting point 1975 ℃. Soluble in acid. Sodium hydroxide. Ammonium chloride, insoluble in water, ethanol and ammonia. Is an amphoteric oxide. In the air to absorb carbon dioxide and water to produce zinc carbonate, yellow. Yellow when heated, white after cooling. Not through the UV, hydrogen sulfide unchanged black.
Uses: used as a white pigment, used in printing and dyeing, paper making, matches and the pharmaceutical industry. In the rubber industry as a natural rubber, synthetic rubber and latex vulcanization activators, reinforcing agents and colorants. Also used in pigment zinc chrome yellow, zinc acetate, zinc carbonate, zinc chloride and other manufacturing. In addition, also for electronic laser materials, phosphors, feed additives, catalysts, magnetic materials manufacturing.
Method: Indirect method: The zinc ingots heated to 1000 ℃, melt gasification, the introduction of hot air oxidation, generating zinc oxide, after cooling, cyclone separation, the fine particles with a cloth bag. That is prepared zinc oxide products.
