| 摘 要： | 用改进的 Pechini 法合成 Ca_(0.28)Li_(0.15)Sm_(0.28)Nd_(0.15)TiO_3(CLSNT)陶瓷粉体。采用 TG、DTA、XRD 和 SEM等技术对 CLSNT 陶瓷粉体进行分析。在 600℃预烧 3 h 后,钙钛矿结构的 CLSNT 相形成,但有少量 Sm_2Ti_2O_7、TiO_(1.49)、Ti_3O_5、Ti_4O_7 相。预烧温度升高到 1 000℃,只有钙钛矿结构的 CLSNT 相。用这一方法能在相对低的温度下制备出性能优良的微波介质陶瓷。在 1 230℃下烧结 3 h,εr为 98,Q·f 为 6 360 GHz,τf 为 8×10–6℃–1。

| Abstract: | Ca0.28Li0.15Sm0.28Nd0.15TiO3(CLSNT) ceramic powder was synthesized by the modified Pechini method. The ceramic powders were characterized by TG,DTA,XRD and SEM. After calcined at 600℃ in air for 3 h, the perovskite CLSNT phase formed as the major phase with Sm2Ti2O7、TiO1.49、Ti3O5、Ti4O7 as the subsidiary phase. Heating the precursor to 1 000℃, only the CLSNT with a perovskite structure was detected. Ceramics with excellent microwave dielectric properties could be prepared at lower temperature than that by solid-state reaction method. The CLSNT ceramics sintered at 1 230℃ for 3 h showed microwave dielectric properties of εr= 98,Q·f = 6 360 GHz , τf = 8×10–6℃–1 |
