Abstract
Stable colloidal dispersions with a 2 mM TiS3 concentration (300 mg/l) are obtained by ultrasonic treatment of TiS3 in acetonitrile and isopropyl alcohol and characterized by physicochemical methods. The electrical double layers for the particles in dispersions are estimated from the measured z-potentials, and the energies of interparticle interactions are calculated based on the Derjaguin-Landau-Verwey-Overbeek theory. The structural and spectroscopic identity of the particles and crystalline TiS3 is demonstrated for the solid phases obtained from the dispersions.
