CaO-SiO2-B2O3-Al2O3-La2O3 system sealants with different B/Si ratios of 0.38~0.82 were prepared by high-temperature melting method for intermediate temperature solid oxide fuel cell (ITSOFC). The glass transition temperature (Tg) and softening temperature (Ts) of the sealant were analyzed by TG-DSC. The complex phases of the sealants detected by XRD were consistent with the calculation results generally. The resistivity of the sealants tested by electrochemical workstation was above 65 kΩ·cm2, and the wetting angle was also calculated. The prepared sealants basically meet the sealing requirement for ITSOFC.
