Abstract :
Two sets of silica particles have been synthesized and dispersed in both 1-propanol and toluene-ethanol mixture. The conductivity of the suspensions has been measured as a function of their concentration, by means of a device and experimental procedure developed by the authors. It has been observed that the conductivity increases linearly with the solid fraction for values smaller than 5%. Additionally, the water content has also been measured, to evaluate its effect on the conductivity of suspensions.
