Composition-dependent structure and remnant polarization study of Bi3.25La0.75Ti3-xZrxO12 ceramics B-site substituted Bi3.25La0.75Ti3O12 (BLT) ceramics by Zr, Bi3.25La0.75Ti3-xZrxO12 (BLTZx, x = 0, 0.2, 0.5, 0.75, 1.00, and 1.50) were prepared by solid-state reaction method. X-ray diffraction and Raman scattering were used to characterize their structures. It is revealed that the Zr substitution doesn’t change the layered structures of BLTZx ceramics whereas the tolerance of Zr substitution is limited. With x increasing from 0 to 1.50, the positions of the different Raman modes don’t show obvious shift while the remnant polarization (Pr) varies. It is revealed that the BLTZ0.2 ceramic has the largest Pr, which might provide guideline for searching new materials. The origin of Pr changing is also discussed. |

Bi3.25La0.75Ti3-xZrxO12 陶瓷組成依賴(lài)結(jié)構(gòu)和剩余極化強(qiáng)度的研究 通過(guò)固態(tài)反應(yīng)的方法制備B位有Zr, Bi3.25La0.75Ti3-xZrxO12 (BLTZx, x = 0, 0.2, 0.5, 0.75, 1.00, 1.50) 等取代的Bi3.25La0.75Ti3O12 (BLT)陶瓷。通過(guò)X射線衍射和拉曼散射確認(rèn)結(jié)構(gòu)。結(jié)果顯示,Zr取代的化合物不改變BLTZx陶瓷的層狀結(jié)構(gòu),然而其耐受性有限。x由0到1.50的化合物,拉曼散射位移一樣,但是剩余極化強(qiáng)度(Pr)不同。其中BLTZ0.2陶瓷的Pr最大,為我們找到新化合物指引了方向。同時(shí)也研究了Pr變化的原因。 |

Bi3.25La0.75Ti3-xZrxO12 陶瓷的成分依賴(lài)結(jié)構(gòu)和剩余極化強(qiáng)度的研究 成分變化可以通過(guò)Zr元素取代陶瓷Bi3.25La0.75Ti3O12 (BLT)的B位來(lái)實(shí)現(xiàn),因此本研究通過(guò)固態(tài)反應(yīng)的方法制備成分為 Bi3.25La0.75Ti3-xZrxO12 (BLTZx, x = 0, 0.2, 0.5, 0.75, 1.00, 1.50)的陶瓷材料,并通過(guò)X射線衍射和拉曼散射表征其結(jié)構(gòu)。結(jié)果顯示,Zr取代不改變BLTZx陶瓷的層狀結(jié)構(gòu),然而Zr能替代的程度是有限的。x由0到1.50的化合物,拉曼散射沒(méi)有明顯的漂移,但是剩余極化強(qiáng)度(Pr)發(fā)生了改變。其中BLTZ0.2陶瓷的剩余極化強(qiáng)度最大,可能為我們開(kāi)發(fā)新材料指引了方向。同時(shí)本文也討論了剩余極化強(qiáng)度變化的原因。 |
