Testing and Analysing for the Product of Crystallization Roasting the Surface Modificated Coal Kaolin Powder

The Product of crystallization roasting the surface modificated coal kaolin was tested by SEM, TEM and XRD. The performance changing of the surface surface modificated ultra-fine calcined coal kaolin was analysed from the Process of crystallization roasting. For example the hydrate TiO₂ film on the surface of the basal body particle is turned non-crystal into crystal. The coating film is well-distribufed.
