Ultrafine La(Ca)CrO₃ (LCC) powder was prepared through the glycine–nitrate gel combustion process. It was shown for the first time that the use of relatively inexpensive CrO₃ as a starting material for chromium has potential for the bulk preparation of sinter-active LCC powder. As-prepared powder, when calcined at 700^°C, resulted in LCC along with a small amount of Ca-CrO₄. The calcined powder was found to be composed of soft agglomerates with a particle size of »70–290 nm. The cold pressing and sintering of the calcined powder at 1200^°C resulted in the mono-phasic La0.7Ca_0.3CrO₃ with density »98% of its theoretical value. This is the lowest sintering temperature ever reported for La_0.7Ca_0.3CrO₃. The conductivity of the sintered La_0.7Ca_0.3CrO₃ at 10001C was found to be »57 S/cm in air. The sintering and electrical behavior achieved for La_0.7Ca_0.3-CrO₃ may find application as an interconnect material for high temperature solid oxide fuel cells if problems with chemical expansion and poor conductivity in fuel can be overcome.
