For example: 15% talc powder for daily ceramics (tableware) is tough, translucent, and bright in color. 40-80% talc powder for building ceramics (tiles, tiles, porcelain, etc.) has minimal thermal expansion and wet expansion It has the characteristics of high strength, high intensity, no cracking and beautiful color. Different kinds of talc can be used to obtain different characteristics in ceramics.
