SINTER REACTIVE LANTHANUM CHROMITE AND PROCESS FOR MAKING IT

摘要

A sinter-reactive lanthanum chromite powder is prepared from the lanthanum chromite precursor LaCr1-xMxO3 (Adsorbate). The powder is crystalline, has the formula LaCr1-xMxO3, 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 DEG C in inert or reducing atmospheres. Sintering to such high density at temperatures in the vicinity of 1600 DEG C makes the powder particularly suited for use as interconnect material for solid oxide fuel cells.
