  2. Liquidus and solidus - Wikipedia

    en.wikipedia.org/wiki/Liquidus_and_solidus

    The composition range within which the primary phase remains constant is known as primary crystalline phase field. The liquidus temperature is important in the glass industry because crystallization can cause severe problems during the glass melting and forming processes, and it also may lead to product failure.

  3. Freezing - Wikipedia

    en.wikipedia.org/wiki/Freezing

    Freezing is a phase transition in which a liquid turns into a solid when its temperature is lowered below its freezing point. [ 1 ] [ 2 ] For most substances, the melting and freezing points are the same temperature; however, certain substances possess differing solid-liquid transition temperatures.

  5. Cooling curve - Wikipedia

    en.wikipedia.org/wiki/Cooling_curve

    The amount of energy required for a phase change is known as latent heat. The "cooling rate" is the slope of the cooling curve at any point. Alloys have a melting point range. It solidifies as shown in the figure above. First, the molten alloy reaches to liquidus temperature and then freezing range starts.

    en.wikipedia.org/wiki/Eutectic_system

    A phase diagram for a fictitious binary chemical mixture (with the two components denoted by A and B) used to depict the eutectic composition, temperature, and point. ( L denotes the liquid state.) A eutectic system or eutectic mixture ( / j uː ˈ t ɛ k t ɪ k / yoo- TEK -tik ) [ 1 ] is a type of a homogeneous mixture that has a melting point ...

  9. Ice - Wikipedia

    en.wikipedia.org/wiki/Ice

    An alternative formulation of the phase diagram for certain ices and other phases of water [15] Pressure dependence of ice melting. Most liquids under increased pressure freeze at higher temperatures because the pressure helps to hold the molecules together.
