WebThe difference between eutectic and peritectic is that eutectic is describing the thermodynamic equilibrium conditions where a liquid coexists with two solid phases while peritectic is describes the isothermal reversible reaction of a liquid phase and a solid phase to form a second solid phase during cooling. Above definition taken from WikiDiff A eutectic system or eutectic mixture is a homogeneous mixture that has a melting point lower than those of the constituents. The lowest possible melting point over all of the mixing ratios of the constituents is called the eutectic temperature.
