| Abstract: | This article takes the industry aluminum hydroxide as a raw material,in 500℃ to 600℃,decomposes it into the superfine powderde alumina,in the hydrosolvent,under the ultrasonic wave function,elutes its impurity and separates,passes through this to process repeatedly,finally in 900℃ roasting.The purity is above 99.95%,High-purity superfine powdered alumina of Particle size about 1μm is achieved.Its ingredient,the grain-size distribution and microscopic Structure were tested. |
