Abstract:
    The invention is directed at an apparatus and method for microwave heating of a ceramic such that an adjustable power microwave source (11) for directing microwave power into a continuous throughput microwave cavity (22). The apparatus further includes a microwave power control system (55) for variably controlling the power that is delivered to the microwave cavity. The reflected power detector measures the value of the reflected power from the cavity and compares that reflected power output value to a preset reflected output value to generate an output signal indicative of the difference in measured and set reflected values. The second component of this system comprises a microwave controller that receives the output signal from the reflected power detector controller and adjusts the power of the adjustable microwave so that the reflected power output signal is maintained at or near the preset output signal value.
