摘要
钙钛矿型铁电材料的晶体结构与压力有很大的关系。本文综述了三种最常见最简单的钙钛矿型铁电体Ba Ti O_3、Pb Ti O_3、KNb O_3、稍微复杂的PZT(Pb(Zr_(1-x)Ti_x)O_3)和弛豫铁电体PMN(Pb(Mg_(1/3)Nb_(2/3))O_3在超高压下晶胞参数和晶体结构与压力的变化。对于上述五种钙钛矿型铁电体,随着压力的增加,晶胞参数都变小,发生从铁电相到顺电相的转变。此外,随着压力的增加,还会发生铁电相到铁电相的转变和铁电相的重新出现。
The crystal structures of perovskite ferroelectrics have a great relationship with the pressure.This article summarizes the lattice parameters and the crystal structure of three kinds of the most common and simple perovskite ferroelectrics Ba Ti O_3,Pb Ti O_3,KNb O_3,slightly complex PZT(Pb(Zr_(1-x)Ti_x)O_3)and relaxor ferroelectric PMN(Pb(Mg_(1/3)Nb_(2/3))O_3change under high pressure.For the above five kinds of perovskite ferroelectrics,the lattice parameters all decrease and the phase transition from ferroelectric phase to paraelectric phase occur with the increase of pressure.In addition,with the increase of pressure,the phase transition from ferroelectric phase to paraelectric phase also happens and the ferroelectric phase reemergences.
