Application of Glass Sealant for SOFC Sun Kening1,Zhang Naiqing1,Zhou Derui1,Piao Jinhua1 (1.Harbin Institute of Technology, Harbin 150001, China) Abstract:Glass and glass-ceramic materials were investigated as SOFC seals at 800 ~ 850 ℃. The material was based on the glass and glass-ceramic in the BaO-CaO-Al2O3-SiO2-La2O3-B2O3 system. The sealant has a minimum thermal expansion mismatch......
by the white-light coherence method, and the results revealed that the range of the plastic zone is enlarged with the increasing K(or crack length), while the plastic strain decreased rapidly......
