Al_2O_3/Al composites containing a small amount of tin were prepared by the oxidation of the powder compacts of aluminum and tin coated with MgO powder at 1200° and 1250℃. The composite phase grew mainly on the MgO-coated face of the compacts. The thickness of the composite phase varied with the amounts of coated MgO and tin. The effects of the amount and particle size of the MgO powder on the thickness of the composite phase were explained on the basis of the concentration of magnesium produced by the reaction between MgO and molten aluminum. The volume fraction of aluminum in the composite phase decreased with increasing amount of MgO and increased by the addition of tin. The volume fraction of pore in the composite was less than 3 vol% under usual conditions.
