| Abstract: | Using the magnesium oxide which is prepared by pyrolysis of bischofite,as raw material,magnesium hydroxide is prepared.The effects of reaction time,reaction temperature,liquid to solid ratio and stirring rate on the hydration preparation of magnesium oxide are investigated by means of single factor test and orthogonal test.The optimal hydration conditions are determined through test.The experiment results show that the order of the factors are the followinig temperature,time,liquid to solid ratio.The optimal conditions of magnesium oxide hydration are the following: temperature is 80℃,time is 12 h,liquid to solid ratio of water and magnesium oxide is 8:1,the stirring rate is 300 r/min. |
