Refers to a type of solar heating system which makes use of phase changes in a chemical storage medium. At its melting point, any chemical compound must absorb a quantity of heat in order to change phase from solid to liquid, and at its boiling point,...

The lowest melting point of an alloy or solution of two or more substances (usually metals) that is obtainable by varying the percentage of the components. Eutectic melting sometimes occurs when molten aluminum or molten zinc comes in contact with...

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...
