MODELING OF QUANTITATIVE DTA EQUIPMENT .1. ELECTRIC ANALOG APPROACH

For an electric model, relationships have been established as a function of the DTA baseline shift, the intensity of the signal, the slope of the leading edge, the heating rate, the thermal resistance of the heating disc built into the DTA apparatus, the contact resistance between the disc and the sample holders, and the heat resistance between the two measuring sites. Some of the relationships obtained supported knowledge acquired earlier by other approaches, and some furnished new information. The limits of use of this simple model are indicated. © 1979 Wiley Heyden Ltd., Chichester and Akadémiai Kiadó, Budapest.
