Barium-Magnesium-Strontium-Based Glasses Electrolyte Interface

2 Barium-Magnesium-Strontium-Based Glasses/Electrolyte Interface 

Extensive cracking is observed for the BMAl-YSZ interface and it also propagates within bulk YSZ. Even the glass-ceramic consisted of extensive porosity. In contrast to this, BM12 glass exhibited excellent sealing with the YSZ at SOFC

Ba-Ca-Sr (BCS) composition G73 (Ba-Ca-Sr-Al-Si-B) also revealed complete wetdng behaviour with the YSZ interface. The seals remained hermetic even after rapid quenches ( 25°C s ) after 100 thermal cycles between 750°C and
