What is the color of zinc oxide when it is hot and when it is cold is
We know that in pure state, zinc oxide appears as white oxide. In nature, it occurs as ore zincite that comprises manganese and other impurities, which gives yellow to red color to zinc oxide. Zinc oxide in its crystalline state is thermo-chromic, turns from white to yellow when heated and on cooling it turns white.
What is the color of Zinc oxide? - Toppr
Pure ZnO is a white powder, but in nature, it occurs as the rare mineral zincite, which usually contains manganese and other impurities that confer a yellow to red color. Crystalline zinc oxide is thermochromic, changing from white to yellow when heated in air and reverting to white on cooling
