摘要:

分析了国产及日本产PTCR(热敏电阻)元件作为电冰箱压缩启动器时,其恢复时间差异的原因.实验时分别取日本产金红石结构和国产锐钛矿结构的TiO2为原料,与同种国产BaCO3粉末反应,采用同样的电子陶瓷烧结工艺制备PTCR样品.分析启动元件电阻-温度特性曲线发现:国产PTCR元件高温时的温度系数αT低于日产样品,国产启动器恢复时间较长是由于制备国产样品的主要原料TiO2是锐钛矿结构,而日产样品则是金红石结构.TiO2粉体晶型结构对BaTiO3基PTCR材料电阻温度系数有一定的影响.

Abstract:

The reasons for the difference in recovery time between domestic and Japanese PTCR (thermistor) components as refrigerator compression starters were analyzed. In the experiment, TiO2 of Japanese rutile structure and domestic anatase structure were taken as raw materials, and PTCR samples were prepared by reacting with the same domestic BaCO3 powder and using the same electronic ceramic sintering process. Analyzing the resistance-temperature characteristic curve of the starting element, it was found that the temperature coefficient αT of the domestic PTCR element at high temperature was lower than that of the Nissan sample, and the longer recovery time of the domestic starter was due to the fact that the main raw material TiO2 for the preparation of the domestic sample was anatase structure, while the Nissan sample was rutile structure. The crystal structure of TiO2 powder has a certain effect on the resistance temperature coefficient of BaTiO3-based PTCR materials.
