| ABSTRACT |
|
In this study, aluminum sec-butoxide, aluminum iso-propoxide were mixed with alcohol such as, secbutanol, iso-propanol. And then Acetyl Acetone, water were added to make Acetyl bond and OH bond. After that, Polymeric alumina sol was synthesized from catalysis reaction with strong acid typically HCl. These alumina soil was dried at 8$0^{circ}C$~9$0^{circ}C$ to have a optmum viscosty for spinning, spinned at spinner, and then sintered to make polycrystalline alumina fiber. |
