The point, with coordinates
critical solution temperature and critical composition, on a temperature-composition phase diagram at which the distinction between co-existent phases vanishes. In solid-solid, solid-liquid and liquid-liquid systems both upper and lower
critical solution temperatures and corresponding
critical solution compositions can occur. Synonymous with
consolute point.
