1. A method, comprising:
providing a first reactant, wherein the first reactant comprises a first metal, the first metal is selected from the group consisting of Li, Be, Na, Mg, Al, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Rb, Sr, Y, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Cd, In, Sn, Cs, Ba, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, TI, Pb, Bi, Po, Fr, Ra, Ac, Th, Pa, U, and a lanthanide, and the first reactant is metallic or is a metal compound;
providing a second reactant, wherein the second reactant comprises a second metal, the second metal is selected from the group consisting of Li, Be, Na, Mg, Al, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Rb, Sr, Y, Zr, Nb, Mo, Ru, Rh, Pd, Ag, Cd, In, Sn, Cs, Ba, Hf, Ta, W, Re, Os, Ir, Pt, Au, Hg, TI, Pb, Bi, Po, Fr, Ra, Ac, Th, Pa, U, and a lanthanide, the second reactant is metallic or is a metal compound, and the second reactant is different than the first reactant;
heating the first and second reactants to a pre-heat temperature, wherein the pre-heat temperature is below an auto-activation temperature and above a minimum compression activated synthesis temperature; and
while maintaining the first and second reactants at the pre-heat temperature, commencing exerting compressive stress on the first and second reactants to initiate a self-propagating high-temperature synthesis reaction between the first and second reactants by the compressive stress and thereby form a product metallic compound.
