High-temperature glassy-ceramic sealants SiO_2-Al_2O_3-BaO-mgO and SiO_2-Al_2O_3-ZrO_2-CaO-Na_2O for solid oxide electrochemical devices

作者： S.Qi N.m.POROTNiKOVA m.V.ANANYEV A.V.kuzmin V.A.EREmiN A.A.PANKRATOV N.G.mOLCHANOVA O.G.REZNiTSKiKH A.S.FARLENKOV E.G.VOVKOTRUB Yu.P.ZAiKOV 北京化工大学材料科学与工程学院北京100029 institute of High-Temperature Electrochemistry of UB RAS Ekaterinburg 620137Russia Ural Federal University named after the First President of Russia B.N.Yeltsin Ekaterinburg 620002Russia

Glasses of the SiO_2-Al_2O_3-BaO-mgO and SiO_2-Al_2O_3-ZrO_2-CaO-Na_2O systems were synthesized in the perspective to apply them as sealants in SOFC at operating temperatures of 700-900 °C. Thermal properties of the chosen glass compositions and their compatibility with the SOFC materials(YSZ-electrolyte and alloy-interconnector Crofer22 APU, 15Х25Т) were investigated by means of synchronic thermal analysis and high-temperature dilatometry. The elemental analysis was performed by atomic emission spectroscopy. The average values of the temperature coefficients of the linear extension are 10.0×10^(-6) °С^(-1) for glass 45%SiO_2-15%Al_2O_3-25%BaO-15%mgO and 9.5×10^(-6) °С^(-1) for glass 60%SiO_2-10%Al_2O_3-10%ZrO_2-5%CaO-15%Na_2O. The gluing microstructure in YSZ/glass/Crofer22 APU was studied by scanning electron microscopy. The crystallization process of silicate phases was revealed to occur in the SiO_2-Al_2O_3-BaO-mgO glass. The analysis of the crystallization products was performed by Raman spectroscopy and X-ray diffraction. Glassy ceramics was proved to possess better parameters in comparison with amorphous glass to be used as a sealant in electrochemical sensors and oxygen sensors. The SiO_2-Al_2O_3-ZrO_2-CaO-Na_2O low-temperature amorphous glass can be applied in SOFC.
