    摘要:

    論文選取Ti4 對PbZrO3進行摻雜改性，采用溶膠-凝膠技術(shù)制備了PZ及PZT干凝膠粉。XRD實驗結(jié)果表明，單一鈣鈦礦型PZ的煅燒溫度為900℃,而單一鈣鈦礦型PZT(95/5)的煅燒溫度為750℃。SEM觀察發(fā)現(xiàn)，經(jīng)900℃煅燒，PZ已被燒結(jié)成陶瓷，且晶界明顯。而經(jīng)750℃煅燒，PZT(95/5)的粒徑約為150 nm。TEM和EDS結(jié)果表明，實驗所制備的粉體為單一鈣鈦礦型的PZT（95/5）反鐵電納米粉。ICP-OES測定了Ti4 的含量。DSC-TGA實驗結(jié)果表明，由于Ti4 的添加，形成大量Ti4 羥基類物質(zhì)。Ti4 羥基類物質(zhì)的分解，放出了大量的熱，促進了PZT（95/5）的結(jié)晶。

    Abstract:

    Ti4 was selected to modified PbZrO3, and sol-gel method was used to prepare PZ and PZT (95/5) dried gel powder. XRD results showed that the calcination temperature of PZ is 900℃ with single perovskite structure, while that for PZT (95/5) is 750℃. SEM results showed that PZ is sintered into ceramic when calcined at 900℃ and the grain boundary is obvious. However, the particle size of PZT(95/5) is about 150nm after calcined at 750℃. TEM and EDS results indicated that PZT (95/5) nano-powder with single perovskite structure is antiferroelectric material. The content of Ti4 was determined by ICP-OES.DSC-TGA results illustrated that a large number of Ti4 hydroxyl substances was formed because of the addition of Ti4 . And with the decomposition of Ti4 hydroxyl substances, a large amount of heat was released, which is conducive to the crystallization of PZT(95/5).
