What is eutectic point?

The eutectic point is the lowest possible melting point of a mixture of two or more substances. It is the temperature at which the liquid phase of the mixture is in equilibrium with the solid phase, resulting in a eutectic reaction. At the eutectic point, the composition of the solid and liquid phases is equal, and any further cooling will result in the formation of solid crystals.

Eutectic points are important in various industries, such as metallurgy, materials science, and pharmaceuticals, as they determine the optimal temperature and composition for the mixing and melting of different substances. The eutectic point is often used in the design and formulation of materials with specific properties, such as alloys and pharmaceutical products.

Knowing the eutectic point of a mixture is crucial for controlling its properties and behavior during processing and use. It helps in adjusting the composition, temperature, and processing conditions to achieve the desired properties, such as strength, hardness, and solubility.
