Nanometer zinc oxide is white hesagonal crystal or powder, tasteless and none toxic.
The prticle size is nanometer, that is the great feature.
Compared with the indirect zinc oxide, the specific surface area is large and the chemical activity is high.
Due to the enlarged specific surface area and retained a certain proportion actve substanc, it can reduce 50%-60% to replace indirect zinc oxide, and meantime, improve the quality,
