Abstract
Aluminum oxide powders containing iron oxide were passed through a reducing oxygen acetylene flame. The resulting spherical particles of alumina coming out of the flame were quenched in water. The above process resulted in reduction of iron oxide dissolved in alumina and formation of large numbers of point defects. Quenching of the alumina spheres led to the quenching of large numbers of nonequilibrium point defects. The number of these quenched-in defects over the equilibrium concentration were estimated by using the sintering techniques. Activated sintering of alumina was observed in the case of aluminum oxide spheres containing quenched-in defects.
