Disclosed herein are particles that include cores (for example, silver or nickel cores) having silver chloride substantially about the external surfaces thereof, each of the cores constituting at least 5 %, by weight, of each of the particles and being composed of a material other than silver chloride. In addition, these particles are substantially non-planar in shape and have substantially rounded edges. Also disclosed are methods for producing such silver chloride particles involving oxidation of all or a part of the outer, silver portion of a silver or silver-coated particulate starting material by treatment with a chloride-containing oxidizing compound, preferably sodium hypochlorite. |
