Abstract
Abstract In the present investigation, the novel glass series xLa2O3-(10-x)Y2O3-15SrO-15CaO-10B2O3-10Al2O3-40SiO2 (x = 2, 4, 6, 8) has been synthesized by melt quenching technique. The characteristic glass temperatures and the inflection point temperature (Tf) for the glasses have been determined by DTA and differential DTA (DDTA), respectively. The activation energy is calculated using Kissinger, Moynihan and Augis and Benett models. Various kinetic parameters such as fluctuation free volume (fg), Hruby parameter (Hr), bulk thermal expansion coefficient (αf) and k parameters are calculated for studying glass stability with varying La2O3/Y2O3 ratio. The amorphous nature and crystalline phase formation has been studied by X-ray diffraction. Furthermore, the coefficient of thermal expansion (CTE) for all the glasses has been calculated. The interaction studies of the diffusion couples of glasses with pre-oxidized Crofer 22APU and 8YSZ have been carried out at 850 °C. 2 LaY glass is very stable and promising potential sealant for the SOFCs.
