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。
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： e r=85.03, Q · f（at 2 GHz）=3 576 GHz and porosity is 1.6%.
