                  Ni dispersed on ThO₂ forms a hexagonal carbide during the synthesis with 6-7% C.  The hexagonal close-packed structure has a=2.64 Å, c=4.32 Å, c/a=1.63.  The paramagnetic carbide is destroyed in vacuo at 210° and forms a ferromagnetic face-centered cubic phase with Curie point=314°.
