Palladium cobalt phase diagram
WebIn electrochemistry, and more generally in solution chemistry, a Pourbaix diagram, also known as a potential/pH diagram, EH–pH diagramor a pE/pH diagram, is a plot of possible thermodynamically stable phases (i.e., at chemical equilibrium) of an aqueous electrochemical system. WebThe palladium–zirconium phase diagram has been re-investigated over its entire composition range. The revised diagram includes two intermediate phases, Pd 4 Zr 3 and Pd 11 Zr 9, which did not appear in previous studies.The crystal structures of the new phases resemble the B2-type structure although the atoms are displaced significantly …
