|| Ceramic nanometer zinc oxide 90TM-AZO is a kind of white or yellowish superfine powder with the average granular diameter of 30 nanometers and the scope of the granular diameter at 10~40 nanometers. It can provide stronger melting-assisting capability than common zinc oxide, reduce the expansion coefficient and surface stress, prevent cracks, raise blare and whiteness. Ceramic nanometer zinc oxide does not need high-temperature calcination, and can be used to make glaze directly. However, due to the small granule of ceramic zinc oxide, large specific area and strong water absorption, it is easy to incur the “freezing glaze” phenomenon due to the increased viscosity when making the glaze, thus affecting use. So, it is necessary to reduce the consumption by 20-30%, and add a small amount of dispersants. Use of ceramic nanometer zinc oxide can create good economic benefits.
