Preparation of platelike nano alpha alumina particles
Source abstract
Abstract
Abstract A novel synthesis process has been developed for producing high purity nonagglomerate nano platelike α-Al 2 O 3 particles. The process mainly utilizes a seed-effect of fine α-Al 2 O 3 grains, worn from the milling mediums and uniformly mixed with the hydrous alumina during grinding, and also utilizes ZnF 2 additive to reduce the transformation temperature and modify the alumina particle shape. The aspect ratio and the average size of Al 2 O 3 particles prepared at 900°C for 1 h is 2–4 and 40 nm, respectively.
