摘 要：To satisfy practical requirements from industrial applications, an alternate route for synthesis compound ultrafine CeO2 powders by wet-solid-phase mechanochemical modification using industrial grade hydrated cerium carbonate as raw material was *** effect of modifier reaction percentage, reaction time, calcining temperature and modifier amount on particle size, density, suspensibility, and hardness of compound CeO2 powder was *** phase evolutions of preparation process were characterized by *** micrograph of the final product shows that compound CeO2 powders obtained are well-dispersed, spherically-shaped, uniformly-sized and submicron-sized *** method is readily available in raw material, low in cost, simple in process, and has great potential for *** compound CeO2 powders of different physical properties can be synthesized by controlling the above-mentioned influence factors in preparation process.
