摘要：
The SiO2-Al2O3-BaO-CaO-B2O3 sealing glasses with 0,5.6,11.2,16.8gB2O3 addition in solid oxide fuel cell(SOFC) were prepared by a conventional route. The effects of B2O3 content on the structure and sealing performance of the glasses(the wettability; the sintering of glass powder; the characteristic temperature of glass and change in thermal expansion coefficient caused by crystallization; the electric properties and sealing surface stability of glass-ceramic) were researched systemically by Fourier infrared spectrum(FTIR), high temperature microscope(HSM), X-ray diffraction(XRD), thermal expansion instrument, electrochemical workstation and scanning electron microscope(SEM). The results indicate that the content of[BO3]increases, but the [SiO4]decreases with the B2O3 content increasing; the variation rule of sealing properties in four kinds of glass depend on the change of their structure, and the glasses with 11.2,16.8g B2O3 addition meet the requirements for SOFC sealing glass, which can be used for the sealing of SOFC single battery. © 2019, Editorial Department of Journal of Building Materials.
