Abstract

Many natural minerals are used as the raw materials required for the manufacturing ceramic ware. Most of the minerals are from Indian mines of Gujarat and Rajasthan states, some of are imported from Russian sub continent. The present paper reports the thermoluminescence characteristics of mineral China Clay collected from Morbi, Rajkot, Gujarat, India. The TL of mineral at various heat treatments was recorded and also 5Gy beta dose was given to each sample prior to TL recording. The mineral is annealed for 1 hour and quenched from 600 and 800oC. It displayed a well resolved peak around 132oC annealing and quenching from 600 and for annealing and quenching from 800oC the TL peak temperature is found around 138oC and 161oC. XRD and TGA of China Clay mineral were reported.
