eutectic

English

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.

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.

describing chemical composition/temperature of a mixture that gives the lowest temperature at which it becomes fully molten

chemistry: describing the thermodynamic equilibrium conditions where a liquid coexists with two solid phases

eutectic (plural eutectics)

Use with the indefinite article is mixed. The dominant usage seems to favour "a eutectic", although "an eutectic" can be found in some texts.

material that has the composition of a eutectic mixture/alloy

temperature of the eutectic

Borrowed from French eutectique.
