| Abstract: | physucal-chemistry property of ultra-fine calcinated coal kaolin particle was studied. The rea-son for ultra-fine calcinated coal kaolin used as basal body of the substitution of titanium dioxide was analysedby the properrty of pigment. The results showed that the properties of high white, high dioptfe,low quantity ofabsorbing linseed oil, high covering ability of ultra-fine calcined coal kaolin are the main reason as the basalbody for the substitution of titanium dioxide. Inaddition,high adsorptive capacity and surface potential of theultra-fine calcined coal kaolin are beneficial to adsorption of the surface modification ageent on the mineralsurface. |
