| Abstract |
| The sintering behaviour of Bayer grade alumina in the temperature
range 1400°-1800°C in a partially reducing atmosphere is reported.
A 1 wt% addition of titania is found to improve the sinterability of
alumina appreciably. The pellet density after two hours of sintering
was the highest at 147S°C. The microstructure of the sintered pellets
showed enhanced but uneven grain growth compared to that of
similar alumina pellets without the titania addition. They also
showed that the titania addition did not form any eutectic phase with
the impurities in the Bayer alumina during the sintering. |
