Abstract: The composite materials of lead titanate ceramics were obtained via sol-gel methods and hydrothermal process. In order to study the effects of sintering temperature and the sintering techniques for the microconfiguration as well as the intensity of ceramics, the dielectric constants, dielectric loss and resistance of ceramics mixture were discussed. In addition, the composite mechanism was discussed in elementary.

Key words: Fibrous lead titanate, Nanometer composite materials, Electric properties
