Abstract
- This is a study based on the assumption that the volatilization of Cr gives rise to the poor sinterability of LaCrO<subscript>3</subscript>. We have studied the effect of buried materials (none, Al<subscript>2</subscript>O<subscript>3</subscript>, La<subscript>2</subscript>O<subscript>3</subscript>, Cr<subscript>2</subscript>O<subscript>3</subscript>, LaCrO<subscript>3</subscript>) on the sinterability of LaCrO<subscript>3</subscript> by conventional sintering in air. It was observed that the sinterability of LaCrO<subscript>3</subscript> in air is largely enhanced by burying with La<subscript>2</subscript>O<subscript>3</subscript> (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<subscript>3</subscript> in air and the volatilization of Cr does affect the sinterability of LaCrO<subscript>3</subscript>.
