Palladium in the internal electrodes of these devices became increasingly unprofitable. Indeed, the cost of palladium has skyrocketed from around $150 per troy ounce in the mid-nineties to over $1000 per troy ounce today. The use of silver/palladium alloy, rather than pure palladium, is one way to lower costs. Another ... View Doc

Expansion. In, for example, palladium-silver alloys, the lattice has already been expanded by the silver atoms, and the PdAg lattice is less influenced by hydrogen and thus less brittle than the pure Pd lattice (Amandusson et al., 2001). A optimal value of the hydrogen permeation rate is reached for a silver content around 25 wt. % Ag ... Read Document
