Eutectic vs Monotectic - What's the difference?

eutectic | monotectic |

As adjectives the difference between eutectic and monotectic

is that eutectic is 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 while monotectic is describes the isothermal reversible change of a liquid phase to form a second liquid phase plus a solid phase during cooling.

As a noun eutectic

is a material that has the composition of an eutectic mixture or eutectic alloy.

Adjective

  • 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.

    Noun

    (en noun)
  • A material that has the composition of an eutectic mixture or eutectic alloy
  • The temperature of the eutectic point
  • Usage notes

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