Ti₄Fe₂C_0.82O_0.18.

ABSTRACT: The phase with composition Ti₄Fe₂C_0.82O_0.18, tetra-titanium diiron carbide oxide, was unexpectedly synthesized by high-pressure sinter-ing (HPS) of a stoichiometric mixture with nominal composition Ti₂Fe. The Ti₄Fe₂C_0.82O_0.18 phase crystallizes in the Fd m space group and can be considered as the Ti₂Fe structure filled with C and O atoms co-occupying the same octa-hedral void [occupancy ratio 0.82 (7):0.18 (7)]. The Ti₄Fe₂C_0.82O_0.18 phase is isotypic with Ti₄Ni₂C and Ti₄Fe₂O_0.407, and is the first example where C and O atoms co-occupy the same site in filled Ti₂
