Ceramic samples of CaF2 were characterized using impedance spectroscopy to understand the effect of porosity on electrical conductivity upto 150°C. Pellets of cold pressed nano powder as well as those sintered at high temperature and transparent ceramic were investigated. The room temperature conductivity of porous samples (cold pressed and sintered at 700°C) were found to be more than less porous samples (sintered at 1000°C and transparent ceramic). The conductivity was found to increase as the temperature is increased till 100°C and decreases on further increase in temperature. At 150°C transparent ceramic sample shows the maximum conductivity.
