  • Preparation of Chromium doped uranium nitride via Sol-Gel and Carbothermic reduction

    2023, Journal of Nuclear Materials
    Citation Excerpt :

    The nitride structure formed is therefore a ternary phase with the stochiometric formula U2CrN3. This phase is present in an orthorhombic crystal structure and belongs to the space group Immm [19]. Theoretical calculations made by Mishchenko et al. [13] have shown that the solubility of CrN in UN crystal is thermodynamically favorable and expected.

    2021, Journal of Nuclear Materials
    Citation Excerpt :

    The U-N and Cr-N bond lengths in the ternary phase are almost the same as the bond lengths in UN and CrN. When a chromium atom replaces the uranium atom in the lattice of the face-centered cubic UN, the bond length decreases from 2.45 Å for UN to 2.07 Å for CrN causing the distortion in the original lattice [44]. The distortion in the lattice caused by Cr replacement in uranium site seems to limit the amount of solution to 33 at%, forcing the Cr to only occupy the 2nd nearest neighbours (NN).

    C3N4, C11N4 and BC2N [3] and the recently proposed BCN3 [4]. Regarding nf based nitrides: n = 4 for Ln (lanthanides) and 5 for Ac (actinides) a few ternary compounds were identified and studied like Ce2TN3 (T = Cr, Mn) [5,6] and A2TN3 (A = Th, U) [7]. Focusing exemplarily on a lanthanide and an actinide, the isostructural ternaries A2CrN3 (A = Ce, U) crystallize in the orthorhombic Immm space group (SG).
