Abstract:
A palladium-containing particulate product having resistance to oxidation of palladium in the product, the particulate product comprising:particles including a metallic phase comprising greater than about 10 weight percent palladium said particles having a weight average size of from about 0.1 micron to about 4 microns;wherein, said metallic phase is substantially polycrystalline with a mean crystallite size of larger than about 50 nanometers and said particles are such that when said particles are heated in an atmosphere of industrial grade air at atmospheric pressure to a temperature of 900.degree. C. at a heating rate of about 10.degree. C. per minute during thermogravimetric analysis, said particles demonstrate a maximum weight gain of no greater than about 40 percent relative to a theoretical weight gain for complete oxidation of said palladium in said particles.
