Abstract
Ceramic parts may be bonded by forming bonding layers of silicon dioxide, silicon, metal or metal oxide on the parts, placing the bonding layers adjacent one another and heating in an oxidizing ambient atmosphere to form an oxide bond therebetween. Pressure may be applied between the ceramic parts to aid in bonding. A reliable bonded ceramic structure is thereby provided.
