酒石酸锌铁电功能材料及其制备方法
摘要：
本发明公开了酒石酸锌铁电功能材料，该酒石酸锌铁电功能材料分子式为[Zn(H2O)(C4H4O6)2/2]·2(H2O)]，具有C2空间群结构，该铁电功能材料为能通过100目筛的单斜晶系白色粉体，纯度不低于99％，该铁电功能材料的电滞2Ec值为24.3kV·cm-1，2Pr值为1.96μC·cm-2，Ps值为0.46μC·cm-2；这样该酒石酸锌铁电功能材料符合铁电功能材料的空间群结构，且其Ps值远远大于罗息盐的Ps值0.25μC·cm-2，具有更显著的铁电特性，所以本发明是一种铁电特性较好的新的铁电体。
摘要（英）：

The present invention discloses a zinc tartrate ferroelectric materials, the molecular formula is [Zn(H2O)(C4H4O6)2/2] 2(H2O)], comprising C2 space-group structure, the ferroelectric material is monoclinic white powder capable of passing sieve of 100 meshes, the purity is not less than 99%, electric hysteresis 2 Ec value of the ferroelectric materials is 24.3 kV cm<-1>, 2Pr value is 1.96MuC cm<-2>, Ps value is 0.46 MuC cm<-2>; this way the zinc tartrate ferroelectric materials conforms to space group structure of ferroelectric materials, and its Ps value is far larger than the Ps value 0.25 MuC cm<-2> of rochelle salt, and possessing obvious ferroelectric properties, so the invention is a novel ferroelectric with good ferroelectrics.
