摘要	A novel surface modified complex strontium titanate used as dispersion particles in an electrorhelogical fluid with an extraordinary high yield stress was synthesized by means of a modified sol-gel technique and characterized by X-ray powder diffraction. The structure model free full profile fitting technique was used to derive the crystallographic data of the compound, which crystallized in a monoclinic lattice with a = 13.6822(7), b = 14.5549(6), c = 12.7423(5) Angstrom and beta = 91.803(2)degrees. Deliberate examination of the XRD pattern indicates that the most probable space group of the compound is P2(1)/n. A possible composition of the complex strontium titanate is Sr[TiO4(C2O4)(2)].3H(2)O with eight chemical formula units per unit cell, leading to a calculated density of D-x=2.25 a/cm(3) in good agreement with the measured density of D-m= 2.28(5) g/cm(3).
