eutectic

EnglishEdit

EtymologyEdit

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

PronunciationEdit

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

AdjectiveEdit

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.

TranslationsEdit

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

• Finnish: eutektinen
• German: eutektisch

• Turkish: birerim, ötektik

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

• Finnish: eutektinen

NounEdit

eutectic (plural eutectics)

1. A material that has the composition of a eutectic mixture or eutectic alloy
2. The temperature of the eutectic point

TranslationsEdit

material that has the composition of an eutectic mixture/alloy

• German: Eutektikum n

• Turkish: ötektik nokta

temperature of the eutectic

Usage notesEdit

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