Abstract

A NEW binary compound in the chrome-urania system has been briefly described by Borchardt1. This compound has been prepared by mechanically mixing 78 weight per cent uranium oxide (UO2) and 22 weight per cent chromium oxide (Cr2O3), pressing the mixture into pellets and firing to 1,250° C. in platinum dishes. The samples were reground and refired and then examined by chemical, optical, and X-ray techniques. A trace of free chrome was observed optically in mixtures where the chemical analysis indicated excess chromium over a Cr: U atom ratio of 1. The X-ray powder patterns indicated only one phase.
