Popis: Nanodisperse modified titanium dioxide ranging in specific surface from 70 to 130 m2/g has been prepared by a sol–gel process using Al(NO3)3 and H3PO4 as modifying components and dodecylamine and ammonium carbonate as structuring components. Microwave drying of an intermediate product and pulverization in a planetary mill have been shown for the first time to be effective in reducing the bulk density of the material and improving its electrorheological activity. The effect of filler concentration (10–40 wt %) on the shear load and leakage current density of electrorheological dispersions has been examined.
