Abstract
Nanoscale α-Al2O3 powder has been prepared by the polyacrylamide gel method. Because polymer-network inhibit the aggregate of Al2O3, nanoscale α-Al2O3 powder with about 10 nm size can be obtained. Its calcination temperature is 1100°C, which is 100°C lower than general calcination temperature in other methods.
