A recording apparatus suitable for thermal and differential thermal analysis was developed. It can be used to obtain data for phase diagram investigations on small samples of rare metals and their alloys at temperatures up to 1500 C. The thermal analysis apparatus consists of a platinum wound resistance furnace with protective atmos phere provisions and a Pt/Pt 13% Rh thermo couple as sensor which feeds a one mV strip chart recorder. A bucking potentiometer used in series with the thermocouple permits a temperature reso lution of better than 0.5 C. For differential thermal analysis, an additional 100 microvolt strip chart recorder is used. The heating or cooling rate can be varied between 0.5 C/min and approximately 15 C/minute. The thermal analysis apparatus was calibrated at several fixed points and has an overall accuracy of =1.5 C. (Author).

Provides a comprehensive introduction to thermal analysis and its usefulness in every area of science from archeology to zoology. Covers many new applications of techniques in TG, DTA, DSC, EGD/EGA, and others. Describes instruments available for each technique, including microcomputers. Includes rewritten chapters on EGD/EGA, miscellaneous techniques, and the determination of purity by DSC.
