  Bi_{4}Ti_{3}O_{12}-PVC composites were fabricated. Ceramics powders of
bismuth titanate were prepared by the sol-gel method using bismuth nitrate
pentahydrate Bi(NO_{3})_{3} \cdot 5H_{2}O and tetrabutyl titanate
Ti(CH_{3}(CH_{2})_{3}O)_{4} as precursors. The Bi_{4}Ti_{3}O_{12}-PVC
composites were fabricated from ceramics powders and polymer powders by
hot-pressing method.
