Abstract
An improved electric field dependent fluid and method of preparing the same for use at temperatures in excess of 100.degree. C. (typically 120.degree. C.) without releasing water comprising: a nonconductive liquid phase; and a dispersed particulate crystalline zeolite phase (e.g., M.sub.(x/n) [AlO.sub.2).sub.x (SiO.sub.2).sub.y ] wH.sub.2 O where M is a metal cation or mixture of metal cations of average valence charge n, x and y are integers and the ratio of y to x is from about 1 to about 5, and w is a variable). Such field dependent fluids are particularly useful in automotive and/or other high temperatures applications.
