BaTiO3系PTCR元件是近年来发展迅速的一种电子器件,高质量的PTCR原料粉体在一定程度上决定了器件的性能.研究并分析了金红石、锐钛矿两种晶型结构的特性差异,同时讨论了BaTiO3基介电材料相变扩张与其相应PTCR材料温度系数αT间的关系.通过对比得出两种晶型的TiO2粉体对BaTiO3系PTCR温度系数的影响,并指出在900～1100 ℃对TiO2粉体进行高温处理完成锐钛矿向金红石的晶型转变后,有利于获得高温度系数的PTCR样品.

BaTiO3 series PTCR components are an electronic device that has developed rapidly in recent years, and high-quality PTCR raw material powder determines the performance of the device to a certain extent. The characteristics of rutile and anatase were studied and analyzed, and the relationship between the phase transition expansion of BaTiO3-based dielectric materials and the temperature coefficient αT of the corresponding PTCR materials was discussed. The effect of TiO2 powder of two crystal forms on the temperature coefficient of BaTiO3 PTCR was obtained, and it was pointed out that the high temperature treatment of TiO900 powder at 1100~2 °C to complete the crystal form transformation from anatase to rutile was conducive to obtaining PTCR samples with high temperature coefficient.
