eutectic
English
Etymology
From Ancient Greek εὔτηκτος (eútēktos, “easily melted”), from εὖ (eû, “well”) + τήκω (tḗkō, “to melt”). Coined as an adjective (along with the noun eutexia) by British scientist Frederick Guthrie in 1884.
Pronunciation

- Hyphenation: eu‧tec‧tic

Adjective
eutectic (not comparable)
- 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.
- (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.
Derived terms
- eutectic alloy
- eutectic mixture
