Abstract
A method of green joining ceramic components is disclosed, particularly for use in forming a discharge body for a ceramic metal halide lamp. The process includes providing a first green ceramic component having a male joining surface, and providing a second green ceramic component having a female joining surface dimensioned to matingly receive the first component. The first and second green ceramic components are assembled along the joining surfaces, the assembled components are uniformly heated to join the first and second components. The joined components are next cooled in a cooling bath that uniformly cools the joined components. Thereafter, the joined green part may be inserted in the furnace for debindering and sintering.
