Progress and new directions in high temperature calorimetry revisited

Abstract

High temperature reaction calorimetry has seen considerable advances over the past twenty years. New and more sensitive calorimeters, improved sample handling techniques, and better control of the final dissolved state has made solution calorimetry and drop solution calorimetry, using molten lead borate and other solvents, very versatile and reliable techniques. This paper summarizes these advances and presents examples of specific applications to problems of transition metal oxide chemistry, high pressure geophysics, melt and glass energetics, and metastable materials relevant to the earth sciences.
