Reaction-Forming Method for Joining SiC-Based Ceramic Parts

A process that involves reaction bonding makes it possible to form strong joints, with tailorable thicknesses and compositions, between high-temperature-resistant structural parts made of SiC-based ceramic materials. These parts and materials are being developed for use as engine components, radiant-heater tubes, heat exchangers, components of fusion reactors, furnace linings, furnace bricks, and components for diffusion processing in the microelectronics industry. The process can be used to join simply shaped parts to make complexly shaped structures, and to repair such parts and structures.
