Abstract
A process for coating a particulate insulating material, e.g. alumina, with a uniform layer of a valve metal. The particles are exposed to a gaseous nitrogen compound, or to nitrogen gas together with hydrogen and a volatile halide of the valve metal. It is thought that nitrogen provides nucleation of the surface for subsequent metal deposition. The coated powder may be used in the fabrication of electrolytic capacitor anodes.
