  • kristalliline tardfaas, mis sisaldab kahte või enamat komponenti faasilisest tasakaalust tulenevates piirides (vt tardfaas; vrd segukristall)
    Good to know
    • Tardfaas, milles ühe (lahustunud) komponendi aatomid on paigutunud teise komponendi (lahustaja) kristallivõresse. Eristatakse asendustardlahuseid, mille puhul lahustunud komponendi aatomid asendavad kristallivõre sõlmpunktides lahustikomponendi aatomeid ja sisendustardlahuseid, milles lahustuva komponendi aatomid paigutuvad lahustikomponendi kristallivõre vabadesse kohtadesse (tühikutesse). (vt sisendustardlahus, asendustardlahus)
  • a solid crystalline phase containing two or more chemical elements in concentrations that may vary between limits imposed by phase equilibrium (see: solid phase; compare: mixed crystal)
    Good to know
    • A crystal consisting of at least two chemical elements, with the foreign atoms distributed statistically within the host lattice. A distingtion should be made between a substitutional solid solution in which the solute atoms are substituted for those of the solvent ans an interstitial solid solution in which the solute atoms are inserted between those of the solvent. (see: substitutional solid solution, interstitial solid solution)
