Due to the limitation of technical and economic conditions, the large amount of magnesium resources in the western salt lake of China has not been effectively utilized so far, and the research and development of magnesium salt products (such as magnesium chloride cement, etc.) is an important development direction for the high utilization of magnesium resources in the western salt lake, which has important economic and social significance.
Reactivat magnesium oxide is an important inorganic chemical product. The preparation of active magnesium oxide by direct calcination of hydromagnesite is a short process and low cost. In this paper, the active magnesium oxide was prepared by direct calcination of hydromagnesite, the activity of magnesium oxide was determined by citric acid method, the effect of calcination temperature and time on the activity of magnesium oxide was studied, the calcination process conditions were optimized, and the effect of the activity of magnesium oxide on the strength of magnesium chloroxide cement was also studied. The microstructure of...
