Thermal stability of the sintered samples of uranium mononitride was investigated in high purity helium atmosphere at 1900° – 2300°С. Thermogravimetry analysis of samples showed that the weight loss in uranium nitride consists of two stages. On first stage decomposition of uranium mononitride and nitrogen release starts. On the second stage additional active evaporation of uranium metal happens. During heating of the samples, nitrogen was registered by mass spectrometry. Microstructure of the samples after high temperature tests showed irregularly distributed spherical particles of uranium metal. |
