ABSTRACT:
An amorphous hydrated metal oxide primer for adhesively bonded articles results in a bond resistant to crack propagation. A plurality of articles at least one of which is ceramic are bonded to one another through a layer of polymeric adhesive. The ceramic article has a layer of amorphous hydrated metal oxide formed by applying and subsequent hydrolysis of a layer comprising M.sub.x OR.sub.y or mixtures thereof. In the formula M.sub.x OR.sub.y, x is 1, y is 3 or 4, M is any metal capable of forming a stable alkoxide and R is an organic radical. The bonded joint is preferably made by applying to a surface of at least one ceramic article a layer of M.sub.x OR.sub.y described above. The ceramic article having a layer of metal alkoxide is exposed to moisture and a temperature of about 25.degree. C. to about 300.degree. C. and adhesive is placed in contact with and between the ceramic article and other article. The two bonded articles are then exposed to pressure and optional heat resulting in a joint resistant to crack propagation.
