For many alloys there is a particular alloy proportion ( in some cases more than one ), called either a eutectic mixture or a peritectic composition, which gives the alloy a unique and low melting point, and no liquid / solid slush transition.

A 5 % emulsion preparation, containing 2.5 % each of lidocaine / prilocaine, is marketed by APP Pharmaceuticals under the trade name "'EMLA "'( an abbreviation for "'Eutectic Mixture of Local Anesthetics "').

Nilson was apparently unaware of Mendeleev's prediction, but Per Teodor Cleve recognized the correspondence and notified Mendeleev . Metallic scandium was produced for the first time in 1937 by electrolysis of a eutectic mixture, at 700 800 �C, of potassium, lithium, and scandium chlorides.

They bear a considerable resemblance to the eutectic mixtures which are formed on the cooling of solutions of mineral salts, and remain liquid till the excess of either of the components has separated out, finally solidifying " en masse " when the proper proportions of the constituents and a suitable temperature are reached.

A commonly used thermal salt is the eutectic mixture of 60 % sodium nitrate and 40 % potassium nitrate, which can be used as liquid between 260-550 �C . It has a heat of fusion of 161 J / g, and a heat capacity of 1.53 J / ( g K ).
26.
They suggest for instance, a eutectic mixture of Mg ( ClO 4 ) 2 and Ca ( ClO 4 ) 2 brines which have eutectics of-71�C and-77�C . This is well below the lowest known temperatures for growth for terrestrial microbes, of-20�C, but growth at lower temperatures may be possible on Mars so long as liquid is present.
27.
Hydrogen peroxide and water form a eutectic mixture, exhibiting freezing-point depression; pure water has a melting point of 0 �C and pure hydrogen peroxide of " 0.43 �C, but a 50 % ( by volume ) solution of the two freezes at " 51 �C . The boiling point of the same mixtures is also depressed in relation with the mean of both boiling points ( 125.1 �C ).
