Did you know?
A eutectic reaction
is an isothermal reversible reaction in which a liquid solution
is converted into two or more intimately mixed solids on cooling, the number of solids formed being
the same as the number of components in the system (e.g., two in a binary system). The word
comes from the Greek eut?ktos
, "easily melted." In the lead-tin system,
the eutectic point is at 73.9 at.% Sn and 183 °C. A eutectic alloy
is one having a
composition that corresponds to the composition at the eutectic point on a phase diagram.
