    摘要:

    論文采用溶膠-凝膠技術(shù)合成了Pb（Zr0.95Ti0.05）O3納米粉，并探討了煅燒溫度對(duì)PZT(95/5)鈣鈦礦相結(jié)構(gòu)穩(wěn)定性的影響。據(jù)TGA-DSC的實(shí)驗(yàn)結(jié)果，確定了干凝膠粉的煅燒溫度范圍為550℃-750℃。XRD實(shí)驗(yàn)結(jié)果表明，隨著煅燒溫度的升高，粉體主晶相的強(qiáng)度逐漸升高，雜質(zhì)相的峰高逐漸減弱直至消失。當(dāng)在750℃煅燒時(shí)，粉體結(jié)構(gòu)為單一的鈣鈦礦相。利用SEM觀察發(fā)現(xiàn)，隨著煅燒溫度的升高，所合成的粉體的尺寸逐漸變小、均勻。當(dāng)在750℃煅燒時(shí)，單一鈣鈦礦結(jié)構(gòu)的粉體的平均粒徑尺寸為100 nm。

    Abstract:

    Pb (Zr0.95Ti0.05)O3(PZT95/5 for short) anti-ferroelectric nano-powder was prepared by sol-gel method，and the effects of calcinations temperatures on structural stability of perovskite for PZT(95/5) was systematically investigated in this paper. Based on the results of TGA-DSC, calcinations temperature range of dried gel was identified as 550℃ to 750℃. XRD results illustrated that the peak intensity of the main crystalline phase gradually increasing, while that of the impurity phase decreasing, eventually disappeared with the increasing of the calcinations temperature T1. When calcined at 750℃, single phase of perovskite for PZT(95/5) was formed. Observed under SEM, with the increasing of T1, powder synthesized becomes finer and more uniform progressively. And when calcined at 750℃, the average particle size of PZT(95/5) nan-powder is about 100 nm.
