Feb 01, 2005· EPA 856490 discloses a specific silvervanadium oxide and its use as cathode material in electrochemical cells. This silvervanadium oxide is produced in a solidstate reaction between silver oxide and a vanadium oxide such as V 2 O 5 or V 6 O 13, at from 500° C. to 520° C. The use of silvervanadium oxide bronzes as oxidation catalyst is also known.
Mar 12, 2016· Iron (Fe) does not reduce very easily and thus mercury does not penetrate or diffuse into the Fe lattice structure as easily as it does with other metals such as gold (Au) and silver (Ag).
