Abstract
Large quantities of nanocrystalline Ti-Ru-Fe-O (2-1-1-2) powder were prepared in a ZOZ attritor. The powder thus obtained contains more than 50 wt.% of hexagonal Ru and Fe 2 Ti. When used as starting material for plasma spray deposition, these phases react together to form B2 cubic structures with various lattice parameters, reflecting change in the stoichiometries. The coating obtained by plasma spraying this powder is adherent on a Fe subtrate. It exhibits a cathodic overpotential for hydrogen evolution (i = -250 mA cm -2 ) in typical chlorate electrolysis conditions of η 250 = -550 mV.
