A METHOD FOR PRODUCING COMPOSITE BODIES HAVING A METAL MATRIX AND A METAL OXIDE DISPERSION IN THE MATRIX COMPRISING, PREPARING A MIXTURE OF SUBMICRON-SIZE MATRIX METAL OXIDE PARTICLES AND SUBMICRON-SIZE DISPERSION METAL OXIDE PARTICLES, REDUCING THE MATRIX METAL OXIDE PARTICLES TO THE METALLIC STATE WHILE RETAINING THE DISPERSION PARTICLES IN OXIDE FORM, SUBJECTING THE METAL-METAL OXIDE MIXTURE TO AN ENVIRONMENT RENDERING THE SUBMICRON-SIZE MATRIX METAL PARTICLES NON-PYROPHORIC, COMMINUTING THE MIXTURE IN A LIQUID MEDIUM NONOXIDIZING TO THE MATRIX METAL AND DISPERSION METAL OXIDE PARTICLES TO REDUCE THE SIZE OF ANY AGGLOMERATES FORMED DURING REDUCTION OF THE MATRIX METAL OXIDE PARTICLES, SHAPING THE MIXTURE TO FORM A GREEN BODY AND FIRING FOR A TIME SUFFICIENT TO REMOVE RESIDUAL LIQUID MEDIA CARRIED FROM THE COMMINUTING OPERATION, AND EFFECTING A SECOND COMPACTION AND SIMULTANEOUS FIRING TO INCREASE THE DENSITY OF THE COMPACT.
