摘要：Fine-grained α-alumina powder with high purity was prepared from boehmite sol with pseudo-boehmite as seed. The effect of the seed on the formation temperature and the particulate properties of α-Al2O3was investigated. The results showed that pseudo-boehmite seed significantly reduced the formation temperature of α-Al2O3. The final α-Al2O3powders had an average particle size of ~250 nm with good dispersity and narrow particle size distribution. With the increase of the seed amount, no remarkable change was observed in the average particle size of α-Al2O3particles, but the particle size distribution became narrower. © 2013 Springer Science+Business Media Dordrecht.
