ABSTRACT:
A method of repairing or joining a metal oxide, such as Al.sub.2 O.sub.3, containing ceramic bodies, fired or unfired by preparing a sol from a precursor of the metal oxide, mixing with a gelling agent, Al(NO.sub.3).sub.3, to form a paste, optionally adding a reinforcement of SiC particulate and heating at an elevated temperature, and a repair kit.
