Zinc Oxide 99.5%

Zinc oxide is a white powder, odorless, tasteless , gritless , dry powder known as zinc white or as the mineral zincite with chemical formula ZnO. Crystalline zinc oxide is thermochromic, changing from white to yellow when heated and in air reverting to white on cooling. This color change is caused by a very small loss of oxygen at high temperatures to form the non-stoichiometric Zn1+xO, where at 800 °C, x = 0.00007.
