PREPARATION AND PROPERTIES OF PbTiO_3 ULTRAFINE POWDERS WITH EPOXY FINE COMPOSITES
PbTiO_3微粉与环氧树脂精细复合材料的制备与特性

In this paper,preparation and properties of the fine composites of PT ultrafinepowders with epoxy in the lower PT content were investigated.The composite samples were ob-tained under applied bias electric fields during solidification.XRD,dielectric frequency spec-trum,light scattering and ultraviolet absorption of samples were measured.The results indicatedthat the influences of solidification field on electric and optical properties of the composites weresignificant.Furthermore,mechanism of electric fields applied on the composities was also dis-cussed.
