| Abstract: | Liquid metal alkoxide was synthesized by using aluminum and special alcohol as raw materials. The effects of vacuum distillation temperature and hydrolysis ratio on the product of alkoxide hydrolysis were studied. The results obtained by XRD, laser particle sizer, and optical microscope show that the phases of the hydrolysis product at different vacuum distillation drying temperature are all boehmite. On the condition of vacuum distillation drying at 54℃ and alkoxide and water molar ratio of 1 ： 3, small size particles can be obtained with very narrow particle size distribution. |
