How to use eutectic in a sentence
eutectic salt alloys closely resemble cryohydrates in behavior.
On remelting, the temperature of solidification is found to be quite fixed, and the mixture is evidently eutectic.
Or, in other cases, we may predict from the curve of melting-points that no eutectic alloy is possible.
This, therefore, is the composition of the eutectic alloy, and it finds its place naturally on the curve given in Fig. 2.
This is the only case in which a eutectic mixture is possible, and it is, of course, found at the lowest point of the curve.

Scientific definitions for eutectic
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.
