Curie Temperature in Piezoelectric Materials

In analogy to ferromagnetic materials, the Curie temperature is also used in ferroelectric and piezoelectric materials to describe the temperature above which the material loses its spontaneous polarization and piezoelectric characteristics. A modified version of the Curie-Weiss law applies to the dielectric constant, also known as the relative permittivity:

Famous quotes containing the words temperature and/or materials:

    —E.B. (Elwyn Brooks)
