Abstract

The dense calcium-doped lanthanum chromites were prepared by liquid mixing method as a SOFC interconnector. A slight, nominal deficit of chromium drastically enhanced sinterability of lanthanum chromite even in air. These samples consisted of perovskite phase and CaO (or La₂O₃). The thermal expansion coefficients of the chromium deficient samples were found to increase with calcium content, from 8.56×10^-6K^-1 to 10.84×10^-6K^-1.
