Abstract
A sinter-reactive lanthanum chromite powder is prepared from the lanthanum chromite precursor LaCr.sub.1-x M.sub.x O.sub.3 (Adsorbate). The powder is crystalline, has the formula LaCr.sub.1-x M.sub.x O.sub.3, where M is magnesium or calcium and x ranges from about 0.03 to 0.3, and sinters to densities higher than about 95% of theoretical density at temperature as low as 1600.degree. C. in inert or reducing atmospheres. Sintering to such high density at temperatures in the vicinity of 1600.degree. C. makes the powder particularly suited for use as interconnect material for solid oxide fuel cells.
