摘要：

The low temperature sintering characteristic of lanthanum calcium chromites has been investigated. A chromium deficient lanthanum calcium chromite, La0.70Ca0.32CrO3, which was prepared by precipitation from nitrate solution using oxalic acid, was found to be sintered easily at low temperatures in air. A relative density of 94% was obtained after heating at 1473 K for 100 h, at 1573 K for 5 h or at 1673 K without holding time. The chromium deficient lanthanum calcium chromite may be used for planar SOFC separators, being applicable to a co-firing fabrication of planar SOFCs.
