ABSTRACT:
The present invention is a fluid which exhibits excellent electrorheological properties at low current densities, at high temperatures, and in the complete absence of absorbed water or water of hydration. In a preferred embodiment, the fluid comprises lithium hydrazinium sulfate dispersed in silicone oil, and in the presence of an appropriate suspension stabilizing agent.
