Ice - Other Ices

Other Ices

The solid phases of several other volatile substances are also referred to as ices; generally a volatile is classed as an ice if its melting point lies above ~100 K. The best known example is dry ice, the solid form of carbon dioxide.

A "magnetic analogue" of ice is also realized in some insulating magnetic materials in which the magnetic moments mimic the position of protons in water ice and obey energetic constraints similar to the Bernal-Fowler ice rules arising from the geometrical frustration of the proton configuration in water ice. These materials are called spin ice.

Famous quotes containing the word ices:

    When all who had money and leisure
    Grew rural o’er ices and wines,
    All pleasantly toiling for pleasure,
    All hungrily pining for pines,
    And making of beautiful speeches,
    And marring of beautiful shows,
    And feeding on delicate peaches,
    And treading on delicate toes.
    Winthrop Mackworth Praed (1802–1839)
