摘要: 研究了等静压诱导掺镧La的Pb(Zr,Sn ,Ti)O3(PLZST)陶瓷材料的铁电-反铁电相变和介电压谱,结果发现介电压谱具有明显的扩散相变和频率弥散的特点,这一现象有利于拓宽人们对压力诱导的多组元弛豫型铁电体的扩散相变行为的认识和理解。Abstract: Hydrostatic pressure-induced ferroelectric-antiferroelectric phase transformation and dielectric properties in PbLa(Zr,Sn,Ti)O3 ceramics were investigated experimentally. Experimental results show that the dielectric properties of the samples versus hydrostatic pressure suggest that diffuse phase transition and frequency dispersion.
