The Gibbs free energies of reaction △rGr of KNbO3 and NaNbO3 were calculated and then that of KxNa1-xNbO3 was estimated.On the basis of the thermodynamic calcu
BaO-CaO-Al2O3-SiO2-La2O3-B2O3 system glass materials were investigated as sealants for a solid oxide fuel cell (SOFC).The transition temperature (Tg) and the cr
