摘要:
研究Y2O3添加量与低温保温温度对BaTiO3基正温热敏电阻(PTCR)陶瓷性能的影响。采用固相法制备BaTiO3基PTCR陶瓷。采用X线衍射仪(XRD)、扫描电子显微镜(SEM)分析陶瓷的相组成及微观形貌。结果表明:低温保温温度为1 045 ℃,Y2O3的添加量(摩尔分数)为0.26%时,陶瓷的温度系数α为0.116 ℃-1,升阻比lg(ρmax/ρRT)为4.1,耐电压强度(E)为76 V/mm。当低温保温温度升至1 090 ℃时,其耐电压强度升至126 V/mm。
Abstract:
The effects of Y2O3 addition and soaking temperature on the properties of the BaTiO3-based positive temperature coefficient of resistance(PTCR)ceramics were analyzed.A series of BaTiO3-based PTCR ceramics were prepared by solid state reaction method.The phase composition and the microstructure of the ceramics were investigated by X-ray diffractometer(XRD)and scanning electron microscope(SEM),respectively.Results showed that the optimal Y2O3 mol content was 0.26% while the ceramics was soaked at 1 045 ℃,the temperature coefficient of resistance α was 0.116 ℃-1,the ratio of lg(ρmax/ρ</sub>RT)was 4.1 and the withstand voltage strength(E)was 76 V/mm.When the soaking temperature was 1 090 ℃,the withstand voltage strength increased to 126 V/mm.
