The Effect of PbO and Se in Different Ratios on Thermal Properties of Bi2Sr2Ca1Cu2Ox BSCCO Glass Ceramic System

Abstract

In this study, thermal properties of Bi2Sr2Ca1Cu2Ox (BSCCO) doped PbO and Se in different ratios has been investigated. The glass transition temperature (Tg), the temperature of crystallization initiation (Tc) and the peak temperature of crystallization peak (Tx) values according to DTA measurements were obtained as 733-749 K, 739-759 K and 746-766 K, respectively. The thermal properties of the samples were determined by Differential Thermal Analysis (DTA). The activation energy values were estimated by using the Kissenger, Takhor, and Augis-Bennett methods, and found to increase with the increasing the amount of incorporation, except PS05 sample. In addition, the thermal stability parameters were calculated by using Mahadevan equality. The PS01 sample is found to be the most stable sample according to the calculations.
