This paper studies the impact on product performance by adding magnesia alumina spinel to aggregate of magnesium complex materials and try to add α-Al2O3 composite powder and Cr2O3.

Other experiments show that the compressive strength and breaking strength of the composite magnesia cements, which are composed of the caustic dolomite and the calcined magnesite according to certain ratio between the caustic dolomite and the calcined magnesite, can be up to or ov.

The microstructure of interface for Mg matrix composites with different enhances were summarized, and the optimization way of interface was discussed.

The advantages of the in situ synthesized composites,as well as the principles,merits and disadvantages and the present research progress at home and abroad of the in situ synthesized Mg matrix composites are presented.
