Abstract
An electrorheological fluid that includes a dispersed particulate phase of anhydrous amorphous ceramic particles. The anhydrous amorphous ceramic particles can be of a very precisely tailored composition that is unavailable in crystalline form, for obtaining enhanced electrorheological response. The amorphous particles are substantially free of water when used, and have reduced tendency to absorb water in use. Accordingly, the electrorheological fluid containing anhydrous amorphous electrorheologically responsive ceramic particles has wide applicability for use, and enhanced durability in such use.
