- Abstract:
-
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.
