The feasibility of preparation for light and activated MgO from Mg(OH) 2 by microwave radiation was investigated. The effects of microwave power, radiation time and material weight on the rate of Mg(OH) 2 decomposing was researched. The best technology on preparation for light and activated from Mg(OH) 2 by microwave radiation was obtained: microwave power was 800W, radiation time was 8 min, material weight was 4g, The calcining time of this process was one tenth as fast as the conventional process. the rate of Mg(OH)2 decomposing was 99.62%. The content of MgO was 95.09%. The iodine value of MgO was 78.68 mg/g.The quality of MgO was up to par of hu Q/HG11-238-82.
