Abstract:
A method of preparing a composition, said method comprising the steps of:(a) placing boron in a compartment evacuated of air and filled with another gas; (b) placing palladium in a cavity overlying the boron in said compartment, wherein the amount of boron is insufficient to form a compound of boron in the palladium and is sufficient to react with oxygen in the palladium while said boron is in solid solution with said palladium; (c) melting the boron and palladium together to form a mixture; (d) cooling the mixture for producing a solidified mixture; (e) turning the mixture over for reversing the vertical locations of the top and bottom portions of the mixture; and (f) repeating steps (c) through (e) until a mixture at the desired homogeneity is attained; wherein the composition is a two-phase palladium-boron composition; wherein the composition is not annealed under conditions that substantially reduce the hardness of the composition.
