Calcined kaolin, as one of the best extenders for titanium dioxide, is mainly used to extend titanium dioxide 

in the system to ensure the full dispersion of titanium dioxide in the system and maximize the covering ability 

of titanium dioxide. Meanwhile, kaolin itself can also provide a certain degree of dry covering power. 

Its particle size is generally fine as 4000 mesh.
