THE MUTUAL SOLID SOLUBILITY OF HAFNIUM CARBIDE AND URANIUM MONOCARBIDE

In contrast to the miscibility gap previously reported for the system HfC-UC, complete solid solubility of these carbides at 2000 c- C was demonstrated. Included are the preparation, heating conditions, x-ray data, and chemical analysis of the starting materials and the solid solutions. (P.C.H.
