Abstract
This article describes the development of a thermogravimeter (thermobalance) based on a multimode microwave cavity utilizing pulse-width modulation control of the power and five figure (0.01 mg resolution) balance. The operation and capabilities of the instrument for the study of thermally induced processes involving mass changes are demonstrated with examples of decomposition, dehydration, and oxidation reactions. The potential for combining microwave thermogravimetry with "sample controlled" techniques is also discussed.
