Abstract
Изобретение относится к устройству анода, предназначенного для использования в электролитической ячейке для производства металлического алюминия из компонента, содержащего алюминий, в электролите в виде расплавленной соли, в которой компонент, содержащий алюминий, в основном представляет собой глинозем и используется электролит из расплавленной соли на основе смеси NaF и AlF, а также CaFи, возможно, галоидов щелочных и щелочно-земельных металлов. В частности, изобретение относится к улучшению анодов, используемых для модификации существующих электролитических ячеек, в которых анод остается инертным при работе. Анод отличается тем, что он имеет форму, позволяющую увеличить площадь его, электрически активной поверхности. Представлено несколько примеров таких конструкций. Анод используется для модификации существующих электролитических ячеек конструкции Холла-Эру для производства алюминия.Международная заявка была опубликована вместе с отчетом о международном поиске.The invention relates to an anode device intended for use in an electrolytic cell for the production of aluminum metal from a component containing aluminum in an electrolyte in the form of molten salt, in which the component containing aluminum is mainly alumina and electrolyte from molten salt is used based on a mixture NaF and AlF, as well as CaFs, and possibly alkali and alkaline earth metal halides. In particular, the invention relates to the improvement of anodes used to modify existing electrolytic cells, in which the anode remains inert during operation. The anode differs in that it has a shape that allows you to increase the area of its electrically active surface. Several examples of such structures are presented. The anode is used to modify the existing electrolytic cells of the Hall-Eru structure for aluminum production. The international application was published along with an international search report.
