Anode and method of production thereof

Abstract: An electrode useful for electrowinning and other processes including evolution of oxygen or chlorine or for plating is formed of titanium particles, compacted cold, and coated and cemented with a first layer of manganese dioxide thermally deposited from Mn (NO3)2 on the grains to form a coating of a combination of manganese dioxide and titanium oxide having a rutile crystal structure, and a further outer layer of manganese dioxide which is electrodeposited, the two coatings not being limited to the surface of the electrode but extending to all exposed surfaces of the grains including those which are walls of channels between the grains The compression of the titanium powder is to a density between 30 and 70 percent of the density of solid metal Solid metal such as metal mesh may be included in the titanium powder prior to compacting, such as expanded titanium metal, to assist in strengthening the form In an alternate embodiment the metal substrate is lead

Compactibility of stainless steel and titanium powders

Abstract: 1. It is shown that, within a given batch of powders, the upper limit of compactibility for stainlesssteel powder produced by the coreduction process and for calcium hydride grade titanium powder rises with increase in the size of the particles in the powder fraction used. 2. It has been established that the maximum porosity of compacts and strip from single fractions of stainless-steel and titanium powders is proportional to the porosity of the powders in the loosely poured condition. 3. An analysis is made of the variation of the mean pore size and the coefficient of permeability with specimen porosity.
