varieeruva keemilise koostisegas vahefaas, mis on lähedane stöhhiomeetriale MX või M2X , kus M on metall, X - mittemetall (taval H, C, N) (vt keemiline ühend, stöhhiomeetria; vrd sisendustardlahus), intermediate phase of a varying chemical composition close to the stoichiometry MX or M2X, where M is transition metal, and X - nonmetal (usually H, C, N) (see: chemical compound, stoichiometry; compare: interstitial solid solution)
