Abstract

Conductive ceramics played an important role in industries and manufactures due to their wide applications on electronics devices. Many synthesis approaches to prepare ceramics have been developing rapidly in the few decades. One of the simple and easy ways to prepare ceramics was using solgel method and varying calcinated temperatures. In this works we developed conductive ceramics, microstructure analysis by XRD and SEM, and conductivity measurement. Our important finding was an improvement in performance of microstructures, crystallinities and conductivities by increasing calcinated temperatures
