Abstract

A filling material for a cell for decomposing alkali metal amalgams comprises mixing carbon particles with one or more heavy metals (as defined), metallic alloys, metallic carbides or metallic oxides or any mixture thereof, the resulting mixture having a metal content below 60% by weight, adding a hydrocarbonaceous binder, heating at a temperature between 900 DEG C. and 1800 DEG C. when the carbon is in the form of graphite and between 1800 DEG C. and 2800 DEG C. when graphitization is needed. The filling material may advantageously include at least one of the metals iron, cobalt, manganese, copper, cadmium and nickel and their alloys. The carbon is preferably pulverulent, e.g. graphite, amorphous carbon, coke or other graphitizable carbon. The hydrocarbonaceous binder can be a fine suspension or gel of carbohydrate compounds or compounds produced by the enzymic digestion of proteins, e.g. albumoses, mono- or poly-saccharides, conjugated saccharides, starch, cellulose, proteins, e.g. gelatines or glues or hydrocarbons such as pitch or tar. Preferably a metallic oxide is added to a paste of coke and pitch to be graphitized and after homogenization is brought to graphitizing temperature. The carbonaceous material so obtained is then reduced to small pieces. The cell used is constituted by a cylinder filled with the filling material of the invention steeped in a caustic liquor, the amalgam being made to run over the filling and pure mercury being discharged from the bottom part of the cell.
