Title:
SPINELLTYPE MIXED OXIDES AND METHOD OF PRODUCING SAME
Document Type and Number:
Japanese Patent JPS5359000
Kind Code:
A
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 CoxFe3-xOn and CoxNi3-xOn, 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.
