Claim 12:
13. A method of forming a plurality of core-shell microparticles or nanoparticles from a dispersion containing a plurality of chromium microparticles or nanoparticles in an acidic solution, the method comprising:
adding a reducing agent to the dispersion including the plurality of chromium nanoparticles, wherein the chromium microparticles or nanoparticles have a first chromium content;
dispersing the plurality of chromium microparticles or nanoparticles within the acidic solution;
adding a metallic acetate chelate to the dispersion, wherein the metallic acetate chelate comprises a metallic material that surrounds the chromium microparticles or nanoparticles to form the plurality of core-shell microparticles or nanoparticles, and wherein the metallic material has a second chromium content that is less than the first chromium content, a shell of the core-shell microparticles or nanoparticles to facilitate sintering of the microparticles or nanoparticles by decreasing a surface energy barrier; and
removing the acidic solution from the dispersion, the dispersion forming an aerosol ink, wherein the aerosol ink includes between 0.1% and 1% by weight of a radical scavenger, the core-shell microparticles or nanoparticles present in a loading amount of 5% to 30% by weight of the aerosol ink.
