Fig. 3: The Raman spectra of UN at high-T.
From: Thermal expansion and degradation of uranium mononitride under high-temperature oxidative conditions
Raman spectra of UN during heating, showing the formation of UO2+x and U2N3 oxidation products (a). After heating to elevated temperatures (b), scans taken after cooling to room temperature showed U3O8 and other oxidation products.
