  Calcined kaolin powder

  Calcined kaolin is a processed inorganic mineral derived from natural kaolinite clay through high-temperature calcination (typically at 800–1000°C) and subsequent grinding.

  This thermal treatment modifies its crystal structure, enhancing key properties such as whiteness, hardness, and chemical stability, while eliminating impurities and volatile components.

  As a result, calcined kaolin emerges as a high-value functional filler, widely acclaimed for its versatile performance in diverse industrial applications.
