ZnO, MgO and SiO_2 powders were covered on top of the alloy as dopants, the effects and principles of the dopants were discussed. Based these, SiC particles were made into preforms with different distribution of air holes by changing the granularity of SiC particles and the content of graphite additive, and the oxidation growth of aluminum alloy melt into the air holes within the preform was controlled to prepare SiC/Al_2O_3/Al composite with inerratic shape. And the SiC particles effect principle to the oxidation of SiC/Al2O3/Al composite was studied.
