ABSTRACT A process is disclosed for producing a solid mater- ial which, in some cases, may have a resultant purity of 99.999% or better which comprises con- tacting the solid material at a temperature ap- proaching the melting point of the solid material with a purifying agent which is substantially non- reactive with the solid material to cause the im- purities in the solid material to enter the mater- ial. After cooling, the purified solid material may be separated from the purifying agent and the impurities therein by leaching.
