Phase Diagrams of Binary and Ternary Fluoride Systems

Abstract

Investigations of the equilibrium phase diagrams of metal fluoride systems have existed as a classical scientific effort since Gibbs, Roozeboom, et al. made their major contributions to science around the turn of the century. It remained for the workers in the Oak Ridge Aircraft Reactor Program and later in the Molten Salt Reactor Program to develop the means to acquire definitive data in massive amounts from a variety of interrelated techniques before the complex phase diagrams pertaining to the materials aspects of the Program could be defined with rapidity and precision. Because of their success in developing the experimental methods for investigation of the fluoride systems, the Oak Ridge group is responsible for a considerable fraction of the binary and ternary systems of the metal fluorides for which detailed phase diagrams appear in the literature.
