This paper presents results on the development of a feedback control system for regulating temperature in ceramic samples being heated by microwave energy for the purpose of joining. The main objective of the control system is to prevent thermal runaway in the ceramic samples during heating. Microwave power level and the positions of a movable iris and plunger are the variables being controlled. Results obtained from heating mullite and silicon carbide are presented. These results indicate the ability of the control system to prevent thermal runaway during microwave heating of the samples.
