Thermoluminescence Characterisation of Ceramic Mineral China Clay

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 800 o C . It displayed a well resolved peak around 132 o C annealing and quenching from 600 and for annealing and quenching from 800 o C the TL peak temperature is found around 138 o C and 161 o C . XRD and TGA of China Clay mineral were reported.
