Why are zinc oxides also 99.7, the degree of activation is different?
The indirect method for producing Zinc Oxide particles has a diameter of 0.1 to 10 μm and a purity of 99.5% to 99.7%. The higher the purity, the heavier the unit mass. The difference between indirect Zinc Oxide and direct zinc oxide is that their materials and processes are different. So the field of use is different.
