| 摘 要： | 通过对实验试样的差热分析及XRD分析,得知烧结过程中液相的存在可促使氧化钙与氧化硅形成硅灰石相。硅灰石瓷配方中SiO2过量(w≤10%)及粘土的w≤10%时能有效地降低烧成温度(1 170 ~1 230℃)。研制瓷料介电性能:er = 7.0~9.0,tgd =(1.0~5.0)104,rv≥(2.0~5.0)1013Ω·cm,aε为(0±30)106℃1。

| Abstract: | Based on the results of differential thermal analysis and x-ray diffraction, it is concluded that the existence of liquid phase helps the formation of CaSiO3 phase from CaO and SiO2 during the sintering process. The excessive SiO2 (w≤10%) and clay (w≤10%) may reduce sintering temperature (1 170 ~ 1 230℃) . The dielectric properties of CaSiO3 porcelain are: e r= 7.0 ~ 9.0,tgd = (1.0 ~ 5.0)?04, r v≥(2.0 ~ 5.0) ?1013 W·cm, ae = (0 30) ?06℃1. |
