Abstract
The invention relates to mixed oxides of the spinel type or of similar structure, containing a quantity of boron adapted to reduce the electrical resistance of the oxide by a factor of at least 1000 calculated on the corresponding compound without boron, some of the preferred compounds being selected from compounds of the formulae Co.sub.x Fe.sub.3-x O.sub.n and Co.sub.x Ni.sub.3-x O.sub.n, wherein x is between 0.05 and 3, n is between 3 and 5, containing from 0.05 to 20 atom per cent boron calculated on the mixed oxides, wherein part of the Co,Ni. or Fe may be substituted by an equivalent quantity of magnesium or calcium, said compounds being optionally doped with lithium; electrocatalytically active electrodes made from such compounds and electrical cells containing such electrodes.
