AC conductivity of a green porcelain body was investigated using impedance spectroscopy over a temperature range of 100–950 °C. The results showed that during the heating, conductivity at 100–200 °C increased mainly arising from H+ and OH− io

Most of the energy consumed during the processing of porcelains is accounted by the heating rate, dwell time and cooling rate employed. Efforts are made in this study to lower the total energy consumption, and thereby total emissions, by optimizing t
