2024年10月16日 · China clay or kaolin, is a soft, white, reactive clay which is the result of the weathering of the mineral kaolinite. It is one of the most common and useful clays in numerous segments of industry due to the fact that it has whiteness, fine particle size distribution, and chemical inertness.

Kaolin, or ‘china clay’ as it is commonly called, is a hydrated aluminum silicate crystalline mineral formed over many millions of years by the hydrothermal decomposition of granite rocks. Hydrous kaolin is characterized by its fine particle size, plate-like or …

Kaolin or china clay is a commercial clay composed principally of the hydrated aluminosilicate clay mineral kaolinite. The commercial value of kaolin is based on the mineral’s whiteness and its fine, controllable particle size. Particle size affects fluidity, strength, plasticity, colour, abrasiveness and ease of dispersion.
