Abstract
Abstract Influence of various intermediate oxides on thermal, structural and crystallization kinetics of 30BaO–40SiO 2 –20B 2 O 3 –10A 2 O 3 (A = Y, La, Al, Cr) glasses has been studied. The highest glass transition temperature ( T g ) with high thermal stability is observed in Y 2 O 3 containing glasses as compared to other glasses. The thermal expansion coefficient (TEC) increases with increasing heat treatment duration in all the glasses. The maximum increase in TEC is observed in Cr 2 O 3 containing glass ceramics. FTIR study showed that transmission bands due to silicate and borate chains become sharper with splitting after heat treatment. A selected glass sample (BaCr) has been tested for interaction and adhesion with Crofer 22 APU interconnect material for its application as a sealant in solid oxide fuel cell.
