Electrofreezing

From Wikipedia, the free encyclopedia

Electrofreezing is the tendency of a material to solidify upon being exposed to an external electric field. Electrofreezing was initially introduced by Dufour in 1892.[1] Examples are the electrofreezing of liquid ammonia[2] supposed to be naturally occurring during electrical storms in Jupiter-like planets,[3] and ice χ supposedly being a form of high pressure ice.[4]

Depending on the material, freezing occur only at certain field intensities, above which electric fields are strong enough to induce chemical reactions.[5]
