The characterization of Ba1-xPbxTiO3 ceramics synthesized by co-precipitation reaction of Ba2+-Ti 4+ system with carbonate agent have been investigated. The result indicates that Ba1-xPbxTiO3 are ferro-electric ceramics. Ba1-xPbxTiO3 with low value of x are typical ferro- electric materials, and Ba1-xPbxTiO3 with high value of x are relaxo materials.
