【摘要】 采用固相法和熔盐法（KCl-NaCl 作为熔盐）合成 SrBi₄Ti₄O₁₅陶瓷粉体,用模板晶粒定向技术（TGG）获得具有各向异性晶粒定向排列的 SrBi₄Ti₄O₁₅陶瓷。实验中,着重探讨了流延成型的工艺。分析表明,以预烧温度900℃模板和900℃固相粉体在1200℃烧结合成制得的流延片的取向度（79.52%）较高,定向排列程度较高,但由于实验过程中,添加了大量有机溶剂,所以有许多缺陷存在。以900℃模板在1200℃烧结的流延陶瓷片的介电性能最好。更多还原

【Abstract】 SrBi₄Ti₄O₁₅ ceramic powders were synthesized by molten salt synthesis method（MSS）and conventional solid phase process （CS）.SrBi₄Ti₄O₁₅ ceramics with oriented consolidation of anisotropic particles was prepared by template grain growth （TGG）.In this study,tape casting technique was explored.Experiment results showed,the degree of orientation was higher when SrBi₄Ti₄O₁₅ ceramics was prepared by tape casting at 1200℃ with SrBi₄Ti₄O₁₅ ceramics powders synthesized by MSS and CS at 900℃.However,there are many defects because a large amount of organic solvents are added in the course of the experiment.Dielectric property of SrBi₄Ti₄O₁₅ ceramics prepared by tape casting was the best.更多还原
