Abstract
This invention relates to metal powders. In particular, the invention provides a novel metal-refractory composite powder which will withstand high temperatures, and means for its production. The metals for which the invention will have special application are platinum, palladium, rhodium, ruthenium, iridium, osmium and gold and silver. According to the invention, a metal powder suitable for use at high temperatures comprises an intimate mixture, other than a mere physical admixture, of particles of platinum, palladium, rhodium, ruthenium, iridium, osmium, gold or silver, or an alloy containing one or more of said metals, and particles of a refractory material.
