热处理工艺对正温度系数热敏电阻PTCR批量生产良率影响的研究
|
摘要
通过固相法制备的BaTiO_3系正温度系数热敏电阻(PTCR),由于受到批量原料纯度一致性、批量操作工艺一致性、烧结温度区域可控性以及热敏电阻本身的双晶特性影响,批量生产的热敏电阻片容易出现批次与批次之间的不稳定性以及长期以来困扰生产的产品室温电阻良率问题。本文通过对片式正温度系数热敏电阻(PTCR)烧成瓷片进行热处理,有效地提高了产品良率,同时瓷片密度、电性能、PTC效应等应用关键参数满足要求。
Through the solid phase of BaTiO_3 is prepared by the positive temperature coefficient thermistor(PTCR), due to the batch raw material purity consistency, batch operation process consistency, sintering temperature area controllability and twin characteristic of the thermistor itself influence, batch production of thermistor prone to instability between batch and batch products at room temperature resistance and long production yield. This article through to the chip positive temperature coefficient thermistor(PTCR) firing ceramics for heat treatment, effectively improve the product yield, at the same time, electronic, PTC ceramics density effect applications such as key parameters meet the requirements.
