The effect of the variables involved in the preparation of silica-alumina gels on their morphology has been analysed by experimental design techniques. Relationships between the surface area and pore volume of the gels and the variables with the greatest influence, namely precipitation rate and temperature, impregnation concentration and calcination temperature have been obtained.
