A METHOD OF FORMING A CERAMIC TO CERAMIC JOINT

摘要

A method of joining at least two sintered bodies to form a composite structure includes: providing a joint material between joining surfaces of first and second sintered bodies; applying pressure from 1 kPa to less than 5 MPa to provide an assembly; heating the assembly to a conforming temperature sufficient to allow the joint material to conform to the joining surfaces; and further heating the assembly to a joining temperature below a minimum sintering temperature of the first and second sintered bodies. The joint material includes organic component(s) and ceramic particles. The ceramic particles constitute 40-75 vol.% of the joint material, and include at least one element of the first and/or second sintered bodies. Composite structures produced by the method are also disclosed.
