摘要
Sr、Mg掺杂的LaGaO3是一种具有发展前景的中温固体氧化物燃料电池的电解质材料,由于其机械性能较差,限制了该材料在实际中的应用。文章研究了不同粒度氧化铝分散的Sr、Mg掺杂的LaGaO3的相结构和力学性能,发现加入细氧化铝可以较大地提高该材料的力学性能。
Sr and Mg doped lanthanum gallate is one of the most promising solid electrolytes for solid oxide fuel cells. But the LaGaO3 based materials are mechanically weak in spite of their quite good chemical and electrical properties. In this paper, the phases and mechanical properties of different size Al2O3-dispersed lanthanum gallate are researched. The results indicate that the mechanical strength of the nanocrystalline alumina dispersed LSGM material has been greatly improved.
