The dispersion of calcined kaolin is good. If the grinding grade meets the final requirements, it can be dispersed within the coating system. The dispersion of calcined kaolin is related to the final effect of grinding. If 45 μ m or larger particles are contained in the superfine processing process, it will not be dispersed in the coating system.
However, the study of calcined kaolin in the industry has focused mostly on product development rather than in the monitoring and control of the calcination process. The standard operating procedure in the industry for the quality control of calcined kaolin products is the chemical extraction of soluble Al 2 O 3.
