Summary
We studied three glasses in the La-Al-alkaline earth borosilicate system for their suitability as materials for joining yttria stabilized zirconia (YSZ) ceramics for solid oxide fuel cell (SOFC) applications. We heated specimens of glass on YSZ using two thermal cycles: one to simulate sealing at 1000d̀C followed by operation at 850d̀C with cycling down to 500d̀C and back; and the other a 60 hr treatment at 850d̀C. The heat treatments crystallized all three glasses to some degree. All glasses wet and bonded to the YSZ and showed no evidence of cracking from the thermal cycling. There was evidence of slight interaction between the glasses and the YSZ after the 60 hr heat treatment.
