product description


Zinc Oxide CAS#1314-13-2

Pure zinc oxide is a white, odorless powder free of mechanical impurities. It is insoluble in water but not in organic solvents such as ethanol and ether. It can be dissolved in dilute acids to form zinc salts and also in strong bases to form zincates, demonstrating the characteristics of amphoteric oxides

Product Usage

Zinc oxide is mainly used in the rubber industry (as a vulcanization activator and reinforcing agent), the coatings and inks industry (as a white pigment and rust inhibitor), the pharmaceutical and cosmetic fields (raw material for external preparations and physical sunscreens), and the electronic and photovoltaic industries (transparent conductive films and buffer layers of photovoltaic modules). It can also be used as a food/feed additive (zinc nutrient fortifier), ceramic flux, and adsorbent and photocatalyst in environmental governance.
