Separation methods and their technologies have been developed according to technological necessities. Ceramic membrane is a new method which presents valuable advantages such as mechanical and abrasion resistance, low chemical reactivity, high working temperatures (over 1000°C) and pressures (over 30 atm). Among different methods of membrane forming, electrophoretic deposition on a graphite electrode results in great length / diameter ratio creating systems with a large filtering surface in small volumes. In the present study SnO2 has been chosen because it grains and pores grow without densification. The influence of dispersant concentration, pH and time of deposition on the deposited mass is also analyzed. The deposited mass decreases with higher dispersant concentrations due to the increase in the dispersion viscosity.
