ABSTRACT:
Disclosed are electrorheological fluids having ceramic particles of high ion conductivity and a nonconducting or dielectric fluid. The high ion conductive particle may be a material having the formula A.sub.1+x Zr.sub.2 Si.sub.x P.sub.3-x O.sub.12, where A is a monovalent ion, such as a material comprising at least one selected from the group consisting of Li, Na, K, Ag and Cu; and x ranges from 0 to 3. The liquid phase may include a silicone fluid or mineral oil. In the case of a mineral oil, the oil may also include an amine-terminated polyester to improve stability of the fluid.
