The discovery that eutectic mixtures could be manipulated, depending on the components of the mixture, allows for changes to the crystal structure and solubility of substances.
12.
As you freeze a mixture, then no matter what the original concentration, some of it will remain liquid down to the freezing point of the eutectic mixture.
13.
Silicon's importance in aluminium casting is that a significantly high amount ( 12 % ) of silicon in aluminium forms a eutectic mixture which solidifies with very little thermal contraction.
14.
Conversely, as a non-eutectic mixture cools down, each mixture's component will solidify ( form its lattice ) at a distinct temperature, until all material is solid.
15.
On the other hand, pig iron is the eutectic mixture of carbon and iron and needs to be decarburized to produce steel or wrought iron, which was extremely tedious in the Middle Ages.
16.
Similarly cooling can be accomplished by partial submerging into a cooling bath, filled with e . g . cold water, ice, eutectic mixtures, dry ice / solvent mixtures, or liquid nitrogen.
17.
Various eutectic mixtures of metals, such as Aluminium and Silicon ( AlSi12 ) offer a high melting point suited to efficient steam generation, while high alumina cement-based materials offer good thermal storage capabilities.
18.
Because of this eutectic mixture effect, if you add a tiny amount of perchlorates to the less deliquescent chlorides, this is enough to reduce the minimum relative humidity needed to deliquesce to the eutonic relative humidity for the mixture.
19.
In practice, eutectic mixtures of several chemicals are used, to achieve wider temperature operating range (-10 . . + 60 �C for low-end and-20 . . + 100 �C for high-performance displays ).
20.
Metallic scandium was produced for the first time in 1937 by electrolysis of a eutectic mixture of potassium, lithium, and scandium chlorides, at 700 800 �C . The first pound of 99 % pure scandium metal was produced in 1960.
