| 摘 要： | 分别以sol-gel法和固相合成法引入BCC(BaCuO2+CuO2)烧结助剂制备BaO-Nd2O3-TiO2(BNT)陶瓷采用DTA-TGA、SEM、网络分析仪等对陶瓷微观结构、性能等进行分析。结果表明:用sol-gel法引入BCC的样品经1 100℃烧结后气孔率为1.6%、εr为85.03、Q.f(测试频率2 GHz)为3576GHz,优于固相合成法1150℃烧结样品的性能。

| Abstract: | BaO-Nd2O3-TiO2(BNT) ceramics were prepared with different additives of BCC(BaCuO2+CuO2) by sol-gel method and solid phase sintering method.Micostructure and properties of ceramis were analyzed by means of DTA-TG,SEM and network analyzer.The results show that BNT microwave ceramic added sol BCC can be sintered at 1 100℃,50℃ lower than by solid phase sintering method.Properties of samples sentered at 1 100℃ are: εr=85.03,Q.f(at 2 GHz)=3 576 GHz and porosity is 1.6%. |
