PHASE EQUILIBRIUM DIAGRAMS FOR FUSED SALT SYSTEMS

 

Research on liquid fused salt fuels should begin with phase
equilibrium studies. This report is a summary of the current
status of the fused salt systems which have been under study in
the ANP Chemistry Section during the last several vears.

The inclusion of a phase equilibrium diagram in this report
is not an indication that it represents a finished study. It
has been necessary to minimize the emphasis on several systems
as it became clear that these systems promised small returns to
the ANP fuels program.

Discussions regarding the extent of the study and phase
characteristics of each of these systems are to be found in the
references listed in the Table of Contents.

A large number of people have contributed to an under-
standing of these phase relationships. A partial list of major
contributors to these studies includes C. J. Barton,

F. ¥. Blankenship, L. M. Bratcher, V. 8. Coleman, H. A. Friedman,
H. Insley, B. 8. Landau, T. N. McVay, R. E. Moore, R. F. Newton,

B. J. Sturm, J. Truitt, G. D. White, and W. C. Whitley.
