摘要
采用Ｂｙｅｒ－Ｒｏｕｎｄｙ法，在－１２０℃～＋２２５℃范围内对ＰＺＴ９４／６陶瓷热释电性进行了研究。在３５℃左右出现的热释电电流峰是由ＦＲＬ－ＦＲＨ相变引起的。利用此相变特性，可以获得较大的热释电系数，最大可达１２０×１０－８Ｃ／ｃｍ２·ｋ。
Pyroelectric properties of PZT94/6 ceramics had been investigated in the temperature range from-120℃～+225℃ by Byer Roundy method. The peak on pyroelectric coefficient curve at about 35℃ was associated with F RL F RH phase transition. The magnitude of pyroelectric coefficient, P=120×10 8 C/cm 2·k, was observed in the range of phase transition between F PL and F RH phase.
