Abstract
Densification of alumina has been studied in the present work in presence of La2O3. La2O3 as dopant has been added to the extent of 0.5, 1 and 2 weight % to pure alumina and studied for pressure-less sintering. Pellets of without and with La2O3 containing compositions were sintered at 1550'C 1600'C, 1650'C and then characterized for densification, phase analysis and SEM & EDAX studies. In phase analysis LaAlO3 has been observed in the sintered samples indicating reactions between alumina and dopant phase. Results reveal that La2O3 is not a beneficial sintering additive for alumina in the temperature range of 1550'C to 1650'C
