Palladium-Boron Alloys and Methods for Making and Using Such Alloys
Abstract
A palladium-boron composition and methods of making and using same are provided. In one aspect, the invention comprises an alloy comprising palladium and boron the boron being in solid solution in the palladium and the alloy having a two-phase structure, wherein each phase of the two-phase structure has the same crystal structure has the other phase and has a different set of lattice parameters from the other phase such that the palladium is greatly hardened by the presence of the smaller phase crystals within the spaces between the larger phase crystals. The composition is carefully prepared by a process wherein palladium and an amount of boron sufficient to place the boron in solid solution, but insufficient to combine with the palladium, are placed together and repeatedly arc melted, cooled and turned over until sufficiently mixed. The hardened composition can be used to create thinner membranes for hydrogen purification and improved electrodes for generation of heat energy, and other electrochemical processes.
