<p>An electrorheological fluid composition comprising a dispersion of an aluminosilicate in an electrically highly resistive fluid vehicle, characterised in that the aluminosilicate comprises a) a moiety of empirical formula (Al2O3)b (SiO2)c where b and c are any numerical values provided that the ratio of b/c never exceeds 1, and b) transition metal cations, including those of group IB metals. and optionally comprises a polar adsorbate, eg a crystalline zeolite, a particulate material for use as the disperse phase of an electrorheological fluid, which comprises such an aluminosilicate, and a process for the preparation of such a material.</p> |
