    • 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.5 MSi.sub.4 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, and Ag; and M is a trivalent ion, such as a material comprising at least one selected from the group consisting of Sc, Fe, Y, In, La, Ce, Pr, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu. 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.
    • 公开了具有高离子电导率的陶瓷颗粒和不导电或介电流体的电流变流体。 高离子导电粒子可以是具有式A5MSi4O12的材料,其中A是一价离子,例如包含选自Li,Na和Ag中的至少一种的材料; M是三价离子,例如包含选自Sc,Fe,Y,In,La,Ce,Pr,Sm,Eu,Gd,Tb,Dy,Ho,Er,Tm中的至少一种的材料 ,Yb和Lu。 液相可以包括硅油或矿物油。 在矿物油的情况下,油也可以包括胺封端的聚酯以改善流体的稳定性。
