Product: Mixture of Kaolin products
Origin: Germany
Colour: Grey Powder
Description
Crystal quartz powders are produced by iron-free grinding of processed quartz grains and subsequent air classification. Crystal quartz powders are characterized by their high SiO2 content and a low concentration of Fe2O3 and TiO2.
Applications
Construction ceramics, glazes, enamels, sanitary ware, tableware, grinding wheels, technical ceramics, insulators. With their high purity and individually adjustable fineness Crystal quartz powders improve your bodies and glazes.
