Titanium diboride granules as erosion protection for cathodes

Abstract

The invention relates to titanium diboride granules comprising aggregates of titanium diboride primary particles, wherein the titanium diboride granules have a rounded shape and are fracture-resistant. The invention further relates to a method for producing these titanium diboride granules, the use thereof for covering graphite cathodes in electrolytic cells in Al fused-salt electrolysis or for repairing holes in cathode bases of electrolytic cells and also a method for repairing holes in cathode bases of electrolytic cells.
