Eutectic salts — are mixtures of salts that melt at low tempuratures absorbing a lot of heat. The energy absorbed (and released when they freeze) is due to heat of fusion. They are engineered for and used in thermal energy storage systems, in particular those… … Wikipedia
Eutectic point — The melting point of a mixture of two or more solids (such as an alloy) depends on the relative proportions of its ingredients. A eutectic or eutectic mixture is a mixture at such proportions that the melting point is as low as possible, and that … Wikipedia

Phase Change Material — A phase change material (PCM) is a substance with a high heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. Heat is absorbed or released when the material changes… … Wikipedia
Phase transition — This diagram shows the nomenclature for the different phase transitions. A phase transition is the transformation of a thermodynamic system from one phase or state of matter to another. A phase of a thermodynamic system and the states of matter… … Wikipedia
phase diagram — noun a) A graph, with axes representing temperature and pressure, showing the equilibrium conditions for a given substance to be a solid, liquid or gas. b) a similar diagram for a binary … Wiktionary
