Origin of eutecticfrom Classical Greek eut?ktos, easily fused from eu- (see eu-) + t?kein, to melt ( from Indo-European an unverified form t?k- from base an unverified form t?-, to melt from source thaw) + -ic
fusing at the lowest possible temperature; specif., designating or of a mixture or alloy with a melting point lower than that of any other combination of the same components
a eutectic mixture or alloy
- Of, relating to, or formed at the lowest possible temperature of solidification for any mixture of specified constituents. Used especially of an alloy whose melting point is lower than that of any other alloy composed of the same constituents in different proportions.
- Exhibiting the constitution or properties of such a solid.
- A eutectic mixture, solution, or alloy.
- The eutectic temperature.
Origin of eutecticFrom Greek eutēktos easily melted eu- eu- tēktos melted ( from tēkein to melt )
- The proportion of constituents in an alloy or other mixture that yields the lowest possible complete melting point. In all other proportions, the mixture will not have a uniform melting point; some of the mixture will remain solid and some liquid. At the eutectic, the solidus and liquidus temperatures are the same.
- An alloy or other mixture with constituents in the proportions of the eutectic.
- The melting point of the eutectic.
- 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.
- A material that has the composition of an eutectic mixture or eutectic alloy
- The temperature of the eutectic point
- Use with the indefinite article is mixed. The dominant usage seems to favour "a eutectic", although "an eutectic" can be found in some texts.
From Ancient Greek εὔτηκτος (eutēktos, “easily melted”), from εὖ (eu, “well”) + τήκω (tēkō, “to melt”).
- Trans.) Leadtin eutectic. Magnified 75 o diameters.
- It is evident that every mixture except the eutectic mixture C will have two halts in its cooling, and that its solidification will take place in two stages.
- The two sloping lines cutting at the eutectic point are the freezing-point curves of alloys that, when they begin to solidify, deposit crystals of lead and tin respectively.
- Eutectic point gives the second halt in cooling, due to the simultaneous formation of lead crystals and tin crystals.
