The eutectic point is a specific composition of a mixture of substances that has the lowest melting point. At this point, the components solidify simultaneously at a single temperature, allowing for a unique phase transition. This phenomenon is commonly observed in alloys and certain mixtures of salts. In a eutectic system, when the temperature drops below the eutectic point, the mixture begins to crystallize into distinct solid phases. This behavior is crucial in various applications, including metallurgy and the formulation of pharmaceuticals, where precise melting and solidification properties are essential for product performance.
