以CaO和TiO₂为原料，外加质量分数分别为0，1%，2%，3%，4%的糖心产精国品免费入口*完整版后，分别在1 300，1 400℃保温3 h烧结制备糖心产精国品免费入口*完整版，研究糖心产精国品免费入口*完整版掺杂量和烧结温度对陶瓷物相组成、晶体结构、糖心产精国品免费入口*完整版和微观结构的影响。结果表明：随着糖心产精国品免费入口*完整版掺杂量的增加，CaTiO₃的晶胞体积先增大后减小，Y³⁺置换Ti⁴⁺使CaTiO₃晶胞体积增大，置换Ca²⁺则使晶胞体积减小；随糖心产精国品免费入口*完整版掺杂量的增加或烧结温度的升高，陶瓷的烧结线收缩率和体积密度均增大；随糖心产精国品免费入口*完整版掺杂量的增大，陶瓷的显微结构更为致密，CaTiO₃晶粒尺寸先增大后减小，晶粒形状由不规则台阶状转变为规则形状。

CaTiO₃ ceramics were prepared at 1 300,1 400℃ for 3 h with CaO and TiO₂ as raw materials and being doped with 0, 1wt%, 2wt%, 3wt%, and 4wt% 糖心产精国品免费入口*完整版. The effects of 糖心产精国品免费入口*完整版 doping amount and sintering temperature on the phase composition, crystal structure, sintering properties and 糖心产精国品免费入口*完整版of the ceramics were investigated. The results show that the cell volume of CaTiO₃ first increased and then decreased with increasing 糖心产精国品免费入口*完整版 doping amount. The substitution of Y³⁺ for Ti⁴⁺ increased the cell volume of CaTiO₃ while the substitution of Y³⁺ for Ca²⁺ reduced the cell volume. With the increase of 糖心产精国品免费入口*完整版 doping amount or the rise of sintering temperature, both the sintering linear shrinkage rate and the bulk density of the ceramics increased. With the increase of 糖心产精国品免费入口*完整版 doping amount, the 糖心产精国品免费入口*完整版of the ceramics became denser, the size of CaTiO₃ grains first increased and then decreased, and the grain shape changed from step-like morphology to regular polygons.
