The chemical composition,structure and thermal stability of the spent FCC equilibrium catalyst from an oil refinery were characterized by XRD,FT-IR,DTA-TG,BET,complete chemical analysis,SEM,and XRF.The spent FCC equilibrium catalyst,clay,barium carbonate,and talc were used as the main raw materials to prepare the alumina abrasion-resistant ceramic balls to be used in the powder grinding mill for manufacture of architecture tiles. The results showed that after proper formulation study,the spent FCC equilibrium catalyst could replace industrial alumina to prepare high performance grinding balls.Meanwhile,the various performance indices of the grinding ball could meet the quality standard for similar products,and additionally,the energy saving effect was achieved in the operation of the grinding section,resulting in a successful comprehensive utilization of solid wastes.
