中文摘要：

以传统的玻璃制备方法熔融法制备出适用于固体氧化物燃料电池封接用的B2O3-CaO-BaO-Al2O3-SiO2-La2O3体系微晶玻璃封接材料。球磨sh的时间可以满足对封接材料粉体的制备要求，对应的粒径分别在0．61μm和2．9μm附近，在相应的累积曲线中99％以上小于9μm；微晶玻璃ACl的SEM照片显示片状的六方钡长石晶体从表面向外生长着并在整个微晶玻璃中错乱生长，还夹杂着一些不规则品粒；在650—800℃之间，封接材料的电阻随温度升高而减小，阻抗值均在10^4-10^5.Ω.cm^2范围内，说明封接材料玻璃粉具有相当好的绝缘性能，符合IT—SOFC对封接材料的绝缘性要求。分别对微晶玻璃ACI和多孔的阳极薄片及微晶玻璃ACl和致密的电解质薄片的界面进行了扫描电镜（SEM）测试。测试表明，在800℃热处理100h后，ACl封接材料与阳极材料及电解质材料之间的结合面非常紧密，没有发生明显的化学反应，ACI封接材料具有好的气密性和热化学稳定性。

英文摘要：

BaO-Al2O3-B2O3-SiO2 glass-ceramic sealing material suitable for solid fuel cells was prepared by traditional melting method. The preparation requirements of sealing material can be met after milling 5h, the corresponding particle size is around 0.61μm and 2.9μm, 99% of the particle size is below 9μm in the corresponding cumulative curve; the SEM of glass- ceramic AC1 shows that flaky hexagonal celsian crystals growing from surface to outside, sprawl in the whole glass- ceramic, with a few irregular grains; the resistance of glass-ceramic is reduced with the temperature increasing in the range between 650-800℃ and the impedance value is 10^4-10^5.Ω.cm^2, indicating the glass-ceramic has quite good insulating property and meets the insulating requirements of IT-SOFC. The interface between AC1 and porous anode slice and the interface between AC1 and dense electrolyte slice were tested by SEM. The result indicates that the joint surfaces between AC1 and anode and between AC1 and electrolyte are quite compact after heat-treating 100h at 800℃, without significant reaction, AC1 has high air tightness and thermo-chemical stability.
