Abstract:The starting composition of Bi3Gao.3Pb0.3Sr2Ca2Cu3Ox+y was prepared using Melt- Quenched method. The glass samples obtained were analysed using the Differential Scanning Calorimeter (DSC), Differential Thermal Analysis (DTA) and Thermogravimetric Analysis (TGA) techniques. A high temperature furnace was constructed for annealing of the glass samples which is capable to run at 1200°C. XRD and resistivity-temperature measurements of heat treated samples at different time-temperature combinations were done. The activation energy was calculated to be 158.08 kJ/mol using the non-isothermal DSC results. It was found that the Ga addition into the BSCCO system was not influenced the superconducting transition temperature but increased the thermal stability of the samples.
