The system HfO/sub 2/--Eu/sub 2/O/sub 3/ was investigated at approx. =5 mol % intervals over a temperature range of 960 to 1900/sup 0/C, by X-ray analysis of quenched specimens. Liquidus temperature measurements made over the entire system showed the lowest liquidus temperature of 1930/sup 0/ +- 15/sup 0/C to be located at approx. =96 mol % Eu/sub 2/O/sub 3/. A large fluorite solid solution region was also found to exist at higher HfO/sub 2/ concentrations over the entire temperature range.
