在前人工作的基础上，提出了UO/sub 2/ZrO/sub 2/体系的相图，其中混合氧化物在太阳炉中熔化以避免污染。在氦中熔化的样品和在氦中加热到1350℃后的样品进行了x射线衍射测量。该体系在高温下共晶周围呈现出狭窄的两相区，在较低温度下范围增大。氧化锆的高温形态不能通过加入UO/ sub2 /来稳定。(认证)
A phase diagram was proposed for the system UO/sub 2/ZrO/sub 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 deg 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 fornn of zirconia cannot be stabilized by the addition of UO/sub 2/. (auth)
