FOREWORD

The following temperature-composition diagrams were

constructed from the literature cited in the references. The two

plutonium(III) fluoride diagrams were reported in The Journal of

Inorganic and Nuclear Chemistry by workers at Oak Ridge National

Laboratory, and are included in this compilation with the permission

of the authors. All of the plutonium(III) chloride diagrams have been

reported in the Journal of Physical Chemistry by workers at Los

Alamos Scientific Laboratory. The diagrams have been compiled

in this report for convenient reference.
