Title: Improvements in or relating to metals deposited in flake form and methods of preparing the metals in fine flake form
IPC: B22F9/04
Filed: 1939-02-06
Abstract: 524,744. Flake metal. PHELPS DODGE CORPORATION. Feb. 6, 1939, No. 3845. Convention date, Feb. 4, 1938. Drawings to Specification. [Class 100 (ii)] [Also in Groups XXXVI, III and XXII] Metal is electrodeposited in an aggregate of laminar particles on a cathode coated with a material which selectively wets certain crystal faces of the deposited metal in such manner that growth occurs in two dimensions along definite lattice planes, in the case of copper the 111 planes, and is hindered in the third dimension. A suitable coating material consists of an oxidized fatty acid compound having at least one hydroxyl group, e.g., oxidized castor oil. Boiled linseed oil containing a lead drier and mixtures of Turkey red oil with fatty acids may also be employed. Oxidation may be effected by treatment with hydrogen peroxide, sodium peroxide, potassium permanganate, sulphuric acid or perchloric acid, by blowing with air, by applying the material to the cathode in the form of a fine spray or by absorption from the electrolyte during electrodeposition. Control of the oxygen content is important. The deposit stripped from the cathode is introduced into water agitated by an impeller and by introduction of air. The flakes are thereby disintegrated, the finer particles collecting at the top by froth flotation this being promoted by an oily film by which they are surrounded. The froth is removed and de-watered in a centrifuge or rotary filter and then dried in an inert atmosphere or vacuum. The oily film on the ilakes becomes baked. This film expedites wetting of the flakes by oil when used in a paint. The dried flakes may be mixed with a vehicle such as a resin and ground in a ball mill in an inert atmosphere. A suitable medium consists of 35 per cent. of a short or medium oil alkyd resin in a toluol-xylol thinner.
