Abstract:
A method of preparing grinding media consisting essentially of sintered TiO.sub.2 particles, comprising the steps of:a) preparing base TiO.sub.2 particles;b) coating the base TiO.sub.2 particles with at least one hydrous oxide and drying the coated TiO.sub.2 particles;c) compressing the coated TiO.sub.2 particles to form densified TiO.sub.2 briquettes;d) granulating and rounding the densified TiO.sub.2 briquettes to form TiO.sub.2 particles having substantially rounded edges; ande) sintering the TiO.sub.2 particles to form grinding media consisting essentially of sintered TiO.sub.2 particles.
