A study based on the oxidation vaporization of LaCrO3

Abstract This is a study based on the assumption that the volatilization of Cr gives rise to the poor sinterability of LaCrO 3 . We have studied the effect of buried materials (none, Al 2 O 3 , La 2 O 3 , Cr 2 O 3 , LaCrO 3 ) on the sinterability of LaCrO 3 by conventional sintering in air. It was observed that the sinterability of LaCrO 3 in air is largely enhanced by burying with La 2 O 3 (with a linear shrinkage of 12.5% and a relative density of 86.90%). The energy dispersive spectroscopy (EDS) infers that there is a volatilization of Cr in sintering of LaCrO 3 in air and the volatilization of Cr does affect the sinterability of LaCrO 3 .
