Apparatus for joining ceramics by microwave.

摘要

An apparatus for joining two ceramics using microwave energy, which comprises: a cavity resonator (II) in which the ceramics (20) are placed; a microwave-generating means (I) for producing microwave radiation to be introduced into the cavity resonator; a pressurizing means (III) for pressing the joining surfaces (20l) of the ceramics against each other, and a temperature control means (IV) for controlling the temperature distribution of the ceramics in such a way that the temperature of the ceramics at the joining surfaces is highest and rapidly decreases toward the unjoined ends of the ceramics. The microwave-generating means may include a microwave oscillator, a klystron amplifier, and an isolator. The temperature control means can be dielectric heating means or a combination of a dielectric heating means and a temperature difference-producing means.
