An apparatus for joining two ceramics using microwave energy, having a cavity resonator in which the ceramics are placed; a microwave-generator means for producing microwave radiation to be introduced into the cavity resonator; a pressurizer for pressing the joining surfaces of the ceramics against each other; and a temperature controller 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 is disclosed. The microwave-generator may include a microwave oscillator, a klystron amplifier, and an isolator. The temperature controller can be a dielectric heater or a combination of a dielectric heater and a temperature difference-producer.
