A method for manufacturing a single-element matrix cobalt-based granular media alloy composition formulated as Co<SUB>f</SUB><SUB><SUB2>1</SUB2></SUB>-(M<SUB>u</SUB>O<SUB>v</SUB>)<SUB>f</SUB><SUB><SUB2>2</SUB2></SUB>, M representing a base metal selected from the group consisting of magnesium (Mg), titanium (Ti), vanadium (V), chromium (Cr), manganese (Mn), iron (Fe), nickel (Ni), copper (Cu), zinc (Zn), aluminum (Al), silicon (Si), yttrium (Y), zirconium (Zr), niobium (Nb), molybdenum (Mo), ruthenium (Ru), indium (In), lanthanum (La), hafnium (Hf), tantalum (Ta), and tungsten (W), u and v representing the number of atoms of base metal M and oxygen (O) per oxide formula, respectively, and f<SUB>1 </SUB>and f<SUB>2 </SUB>being mole fractions represented by the equation f<SUB>1</SUB>+(u+v)f<SUB>2</SUB>=1. The method includes the steps of blending a Co-M master alloy powder and a Co<SUB>u'</SUB>O<SUB>v'</SUB> powder into a corresponding (Co<SUB>a</SUB>M<SUB>1-a</SUB>)<SUB>f</SUB><SUB><SUB2>1</SUB2></SUB><SUB>'</SUB>-(Co<SUB>u'</SUB>O<SUB>v'</SUB>)<SUB>f</SUB><SUB><SUB2>2</SUB2></SUB><SUB>'</SUB> formula, and densifying the blended powders.
