A phase diagram is proposed for the system UO 2 ‐ZrO 2 on the basis of earlier work and the results of new studies in which the mixed oxides were melted in a solar furnace to avoid contamination. X‐ray diffraction measurements were made on specimens melted in helium and on the same specimens after heating to 1350°C. in helium. The system shows a narrow two‐phase region about the eutectic at high temperatures which increases in extent at lower temperatures. The high‐temperature form of zirconia cannot be stabilized by the addition of UO 2 .
