Development and characterization of glass-ceramic sealants in the (CaO-Al2O3-SiO2-B2O3) system for Solid Oxide Electrolyzer Cells

► New glass-ceramic formulation for sealing applications. ► Influence of heat treatment on the seal behavior and crystallization process. ► Glass-ceramic/Metal and glass-ceramic/ceramic interfaces and interactions. ► Effect of V2O5, K2O and TiO2 on thermal properties. ► Determination of crystallization kinetic parameters of the selected composition.
