bcc-U alloys with Mo or Zr are more resistant to hydrogen than pure U metal. High pressures of hydrogen are needed to produce hydrides. Amorphous structure of (UH3)1-xMox can be represented as the cubic structure of beta-UH3 type with grain size around 1 nm. (UH3)1-xZrx are formed in the cubic alpha-UH3 type of structure. All the hydrides are ferromagnets, with magnetic parameters (magnetic moments, Curie temperature), which can exceed those of beta-UH3 (0.9 mB/U, 165–170 K). It is deduced that alpha-UH3 has magnetic properties very similar to beta-UH3, despite rather different U–U spacing.
