Definition of eutectic in English:

adjective

Relating to or denoting a mixture of substances (in fixed proportions) that melts and solidifies at a single temperature that is lower than the melting points of the separate constituents or of any other mixture of them.
Example sentences
  • A eutectic mixture has a melting point below room temperature; therefore, both local anesthetics exist as a liquid oil rather than as crystals.
  • When the temperature has been lowered sufficiently, the remaining liquid solidifies as a eutectic structure of austenite and graphite.
  • All children were given a patch of eutectic mixture of local anesthetic, because midazolam does not have analgesic properties, and later were given the nasal spray.
