Scientific definitions for eutectic

eutectic

[ yōō-tĕk′tĭk ]

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.
