Eutectic is a binary system of two substances which are miscible in all proportions in the liquid (molten) phase but do not react chemically. They have the property of lowering each others freezing point. The minimum freezing point attained is called Eutectic point and composition corresponding to Eutectic point is called Eutectic mixture. This type of system is called Eutectic system.

The eutectic point of a mixture is defined as the temperature at which a eutectic mixture freezes or melts. A eutectic mixture is a mixture that melts and solidifies at a single temperature that is lower than the melting points of the individual constituents.

The eutectic point of a mixture is defined as the temperature at which a eutectic mixture freezes or melts. A eutectic mixture is a mixture that melts and solidifies at a single temperature that is lower than the melting points of the individual constituents.

EUTECTIC point is the lowest possible melting point of a mixture of two substance .wereas TRIPLE point is the condition under which three phases of a substance coexist in eqilibrium.
