| Abstract: | This is a study based on the assumption that the volatilization of Cr gives rise to the poor sinterability of LaCrO3. We have studied the effect of buried materials (none, Al2O3, La2O3, Cr2O3, LaCrO3) on the sinterability of LaCrO3 by conventional sintering in air. It was observed that the sinterability of LaCrO3 in air is largely enhanced by burying with La2O3 (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 LaCrO3 in air and the volatilization of Cr does affect the sinterability of LaCrO3. |
