Effect of La2O3 Addition on Sintering of Alumina

Singh, P (2010) Effect of La2O3 Addition on Sintering of Alumina. BTech thesis.



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
