Abstract: 

BaO-SiO2-Al2O3 glass-ceramics containing K2O and B2O3 were prepared using conventional melting of batch powered, quenching in water and crystallization of sintered glass. XRD patterns presented hexacelsian and celsian as two major crystallized phases. Introducing K2O improved crystallization of hexacelsianmore than B2O3.Glass-ceramic structure are studied using FTIR. Inspecting the property of sintered samples of 4% wt K2O+4% wt B2O3 and 2% wt B2O3 amount of additives. Furthermore condensation temperature reduced up to 850?C. Glass-ceramics containing 4% wt. K2O+4%wt.B2O3 exhibited more sinterability in comparison with 2%wt B2O3 samples. SEM micrograph of glassceramic intersections with metallic alloy and electrolyte depicted the connections characteristics.
