Talc is an important ceramic raw material. It is used in ceramic blanks and glazes. As a chemical material, it is introduced into glazes to cool down and improve the roughness of glazes.
Talc as an ingredient can effectively control the thermal expansion of ceramic body. Provides a cheap source of magnesium oxide as a glaze ingredient. Calcined white talc as ceramic glaze material, play a very good whitening effect, improve the whiteness of ceramics.
