Abstract
The present work describes the development of a glass-ceramic in SiO2–BaO–ZnO–B2O3–Al2O3 system. The prepared glass samples were found to have good compatibility to act as a sealant in planar solid oxide fuel cell (SOFC) in terms of coefficient of thermal expansion (TEC) and glass transition temperature (Tg). The crystallization kinetics of present glass samples were investigated by various characterization techniques such as differential thermal analyzer (DTA), Dilatometery, X-Ray diffraction (XRD) and scanning electron microscopy (SEM). The crystallization behavior of the chosen glass samples was influenced by replacing B2O3 with Al2O3. With the addition of Al2O3 there is increase in glass transition temperature (Tg) and glass crystallization temperature (Tc). Also with the addition of Al2O3 crystallization phenomenon is hindered. XRD and SEM study was done at various temperatures for different time durations. The detail of the above discussed study is done in the present paper.
