Effect of Seeding on Preparation of $alpha$-$alpha$-Al2O3 Powders by Boehmite Sol-Gel Process
ABSTRACT
${alpha}$-Al2O3 powder was produced at 1000$^{circ}C$ by the boehmite sol-gel process with seeding 2 wt% ${alpha}$-Al2O3. The processes and mechanisms of fornation of ${alpha}$-Al2O3 was investigated using DTA/TG, XRD, TR spectroscopy and thermodynamic analysis. The specific surface area of the obtained ${alpha}$-Al2O3 was 16.3㎡/g.
