| Abstract: | The production of aluminum by carbothermic reduction of aluminum-bearing materials with the aid of aluminum monochloride decomposition under vacuum is studied, and the effects of reacting temperature, time and the amount of coal are studied emphatically .The result shows that the optimal temperature and time is (1 370℃) and 2h respectively, the optimal coal amount is 1.4 times of the theoretical under the vacuum of 100Pa. |
