Abstract

A process for preparing a lanthanide or actinide-containing tungsten bronze including: (a) heating a solid composition containing a lanthanide or actinide-containing polyoxotungstate in the presence of a reducing agent until the temperature of said solid composition reaches a first predetermined temperature to form a reduced composition; (b) heating said reduced composition in the presence of an inert gas until the temperature of said reduced composition reaches a second predetermined temperature; and (c) maintaining said reduced composition at said second temperature for a predetermined period of time.
