摘要：
A comparative study of the physicochemical properties of nanodispersed TiO2 samples synthesized from TiCl4 by the sol-gel and coprecipitation methods has shown the advantages of the former from the points of view of both the specific surface area and electrorheological response of the obtained filler in 5% electrorheological dispersions. A correlation has been revealed between the temperature of TiO2 treatment (600-800A degrees C) and its structure, phase state and electrorheological response. The maximum shear stress increment has been observed for dispersions of TiO2 samples that contain 7-10 mol % Al and have been thermotreated at 700A degrees C for 3.0-3.5 h.
