“…The accurate measurement of the sample (and for DTA, the reference) temperature is, of course, of vital importance in thermal analysis. Other workers have used devices such as optical pyrometers and gas thermometers, but these were not considered suitable in the current application. The use of microwave heating presents special problems as metal objects cannot normally be placed in a microwave field without either severely distorting it or causing electrical discharges.…”

Microwave Differential Thermal Analysis in the Investigation of Thermal Transitions in Materials

et al. 1999

View full text Add to dashboard Cite

The paper describes microwave differential thermal analysis, a new technique that combines the advantages of microwave heating with the benefits of differential temperature measurement to give a sensitive means of probing the thermal properties of materials as a function of temperature. Details are given of the theoretical background, equipment, design of sample cells, and different modes of operation. Examples are given for a wide range of thermal transitions including fusions, solid−solid phase transitions, and thermal decompositions. The results are discussed in the context of conventional differential thermal techniques.
