摘要： A composition for use with alloys including extra-fine nickel powder dispersed with a hydrophobic inorganic dispersant which is preferably high-purity fumed silica treated with hexamethyldisilazane. The composition prevents the agglomeration of the nickel powder, thereby preventing weaknesses in alloys, like steel for example, formed with the nickel powder. A method for making an alloy with the composition includes mixing the nickel powder with other metals and/or nonmetals and the hydrophobic fumed silica to form an alloy blend, pressing the alloy blend, and sintering the alloy blend.
