| 摘 要： | 以TiO2、ZrO2为改性剂,制备CaO-B2O3-SiO2系微晶玻璃。对其烧结和介电性能进行了研究,并采用XRD,SEM对微观结构进行了探讨。结果表明:添加适量的TiO2或是混合添加TiO2、ZrO2均能改善CaBSi系微晶玻璃的性能。混合添加比单一添加TiO2更有效。结合材料的烧结性能、介电性能和微观结构,以840℃烧成的添加w(TiO2)为2%、w(ZrO2)为2%的试样性能最佳,其εr为7.1、tanδ为3×10–3,在20~400℃之间的热膨胀系数为7.8×10–6℃–1。

| Abstract: | The influence of TiO2 and ZrO2 doping on sintering and dielectric properies of CaO-B2O3-SiO2 system glass ceramic was investigated. The crystalline structure and microstructure were also discussed by XRD and SEM. The results show that the proper TiO2 or mixture of TiO2 and ZrO2 could improve the properties of CaBSi system glass ceramic and the effects of the latter additives are more obvious. The optimal sintering temperature of 840 ℃ are obtained based on the microstructure and the properties of sintering bodies which contained w(TiO2)=2 % and w(ZrO2)=2 %. The material possessed excellent properties: εr = 7.1, tan δ = 3×10–3 at 10 MHz and coefficient of thermal expansion about 7.8×10–6℃–1 at 20 ~ 400 ℃. |
