Chemical properties
Zinc oxide mainly white powder or red zinc ore exists in the form
of. In the small red detection contain impurities such as manganese
ore that present yellow or red. Zinc oxide crystal when heated, can
have a few overflow (**0 ° C oxygen when overflow oxygen atoms
0.**7%), makes the material appeared yellow. When the temperature
drops is restored after white crystal.
