Abstract

898,449. Electrolytic cells. BRITISH ALUMINIUM CO. Ltd. May 1, 1958 [May 1, 1957], No. 13969/58. Divided out of 898,602. Class 41. An electrolytic reduction cell for the production of aluminium comprises two spaced anodes 2 and at least one solid current-conducting element 6 disposed substantially midway between the anodes 2 and extending from above the cell into the pool 5 of molten aluminium on the floor of the cell, each element 6 containing at least 90% by weight of at least one of the materials in the group consisting of the carbides and borides of titanium, zirconium, tantalum and niobium. The cell comprises a container 1 composed of hot-pressed silicon carbide or of silicon carbide bonded with silicon boride, and a sleeve 7 on the element 6 is of the same material as the container 1. The anodes 2 are carbon and are in parallel rows separated by a row of elements 6, hangars 8, 11 being connected respectively to positive and negative bus-bars the direction of current flow in which is arranged to produce magnetic fields which tend to neutralize each other, and the bus-bars may be adjustable to vary their heights above the cell. If a carbide is employed for the element 6, the oxygen content should be less than 1% by weight, and the free carbon content should not exceed 0.5% by weight if the porosity exceeds 10% by volume. If borides are employed, boron may be added to the aluminium 5 by amounts of 0.001% to 0.003% by weight, or the metal of the boride concerned may be added in amounts of 0.001% to 0.005% by weight. Reference has been directed by the Comptroller to Specifications 784,695, 784,696 and 802,905.
