Abstract :
Electroactive ceramic/polymer composites with 0-3 connectivity pattern have been studied recently in view of their attractive properties for smart sensors applications. Sol-gel processing is a convenient technique to obtain ceramics of high purity and molecular homogeneity. A further advantage is the use of lower processing temperatures than that of the conventional mixed oxides route. In this work we have synthesized lead titanate (PT) and calcium modified lead titanate (PTCa) ceramic powders by this technique. Various techniques have been used to evaluate the characteristics of the resulting ceramics
