Experimental techniques in high temperature thermodynamics

Abstract

An overview of the most recent developments of experimental techniques used in high temperature thermodynamics will be given. Calorimetric, EMF, and vapor pressure methods will be discussed with special emphasis on solid electrolyte galvanic cell techniques and Knudsen effusion mass spectrometry. The essential criteria for the satisfactory application of solid electrolyte galvanic cell methods will be presented and the principal electrolytes presently in use will be surveyed. Special variations of the cell technique used in thermodynamic studies are described. With respect to vapor pressure methods the focus will be on the fundamentals of the Knudesen effusion mass spectrometry. Recent methodic developments were less due to radically new techniques but more to automated control, data acquisition and processing. © 1992, IUPAC
