摘　　要：研究了TiO2添加剂对CaO陶瓷抗水化性能的影响。结果表明:TiO2与CaO反应生成的Ca3(TiO7)连结CaO晶粒,促进固相烧结,增大了陶瓷的烧结密度,同时TiO2能促进CaO晶粒长大,提高了CaO陶瓷的抗水化性能。提高烧结温度,能提高陶瓷密度,从而提高CaO陶瓷的抗水化性能,实验中TiO2最佳添加量为3%。The influence of TiO2 additives on the hydration resistance performance of CaO ceramic was studied. The results showed that the reacted products Ca3 （TiO7） by TiO2 and CaO linked CaO grain and promoted solid-phase sintering, which improved the density of ceramic. And, TiO2 can improve the CaO grain growth, which improved the hydration resistance of CaO. The density of ceramic increased with the sintering temperature increasing, then improved the hydration resistance of CaO. The optimum substitutability was about 3% .
