Qinghai Institute of Salt Lakes, Chinese Academy of Sciences, Xining , China ; 2. The Graduate University of Chinese Academy of Sciences, Beijing , China) Abstract Magnesium resources in salt lakes in China are of high grade, large reserves and easy exploitation. However, their utilization is lagged behind, affecting the sustainable exploitation and comprehensive utilization of other resources in salt lakes to some extent. In this paper, by considering the characteristics of magnesium resources in salt lakes in China, the research progress in the preparation and utilization of magnesium hydroxide, magnesium oxide, magnesium metal and alloys, magnesium oxychloride cements, and magnesium compound whiskers is reviewed. Some suggestions on the exploitation and comprehensive utilization of the magnesium resources in salt lakes in China are raised. Key words salt lake ; magnesium hydroxide ; magnesium metal ; magnesium oxychloride cement ; magnesium compound whisker Contents 1 Introduction 2 Preparation and applications of magnesium hydroxide 3 Preparation and applications of magnesium oxide 4 Preparation and applications of magnesium metal and alloys 5 Preparation and applications of magnesium oxychloride cements 6 Preparation and applications of magnesium compound whiskers 7 Conclusion and suggestions 1, (MgCO 3 ) (MgCO 3 CaCO 3 ), : (kzcx22yw2115) (20072G2153) 3 3 Corresponding author e2mail com
