信中描述的工作源于对使用铀氧化物作为核燃料的兴趣。作者综述了关于UN-YN体系、UN和U/sub2/N/sub3/-稀土氮化物体系互溶度的研究现状。LAN、CEN、NDN和GDN的相互溶解度问题仍然不清楚,这是所述工作的目的。文中介绍了所用材料和测量方法,并给出了在N/SUP2/30bar压力下1300/sup 0/和1800/sup 0/C的测量结果。结果表明,在1300/SUP0/C以上,所研究的四种化合物都是完全互溶的。气温较低时的情况仍不明朗。
The work described in the letter arose out of interest in the use of uranium oxides as nuclear fuel. The author reviews the previous state of knowledge of the mutual solubility of UN-YN systems and of UN and U/sub 2/N/sub 3/ - rare earth nitride systems. The question of the mutual solubility of LaN, CeN, NdN and GdN remained unclear and is the object of the work described. The materials used and the methods of procedure are described and results of measurements between 1300/sup 0/ and 1800/sup 0/C under N/sub 2/ pressure of 30 bar are given. It is concluded that above 1300/sup 0/C all the four compounds investigated are fully mutually soluble. The conditions at lower temperatures remain unclear.
