Etymology[edit]

From Ancient Greek εὔτηκτος (eútēktos, easily melted), from εὖ (, well) + τήκω (tḗkō, to melt).

Pronunciation[edit]

  • (US) IPA(key): /juˈtɛk.tɪk/
  • Hyphenation: eu‧tec‧tic

Adjective[edit]

eutectic (not comparable)

  1. Describing the chemical composition or temperature of a mixture of substances that gives the lowest temperature at which the mixture becomes fully molten. A further requirement is that that temperature is lower than the melting point of any of the pure component substances.
  2. (chemistry) Describing the thermodynamic equilibrium conditions where a liquid coexists with two solid phases.
    For a mixture with two components at a fixed pressure, the eutectic reaction can only happen at a fixed chemical composition and temperature, called the eutectic point.
