Kinetic and microstructural studies of thermal decomposition in uranium mononitride compacts subjected to heating in high-purity helium

Autor: A. V. Tenishev, V. G. Baranov, V V Mikhalchik, Artem Lunev

Publikováno v: Journal of Nuclear Materials. 475:266-273

Although uranium mononitride has a high melting point (≈3100 K), it often decomposes well below this temperature. The threshold and kinetics of thermal decomposition depend on samples' chemical content and on gas environment. However, most experime
