Abstract

This paper deals the effects of some factors on the fabrication process of high purity α-Al₂O₃ from Tan Rai Al(OH)₃. The obtained results of surface morphology (SEM), crystal structure (XRD), composition (EDX) of the original Al(OH)₃ and Al₂O₃ show that Al(OH)₃ washed with CH₃COOH 2N is best at 80oC, efficient Dissolution reached the highest when using 25% HCl, Al₂O₃ calcined at 1400^oC for 2 hours. The obtained Al₂O₃ has the structure α-Al₂O₃, the high purity.
