Controlling the pore size of ceramic microfiltration membranes by varying the degree of flocculation of the coating suspension
article
Ceramic microfiltration membranes or rather filters are used in a growing number of applications. The optimum pore size for these applications ties roughly between 0.1 and 0.5 pm. The pore size of the membranes can be controlled, for example, by the size of the powder particles used or by the size of particles added and burned out later during sintering. We have investigated the possibility of controlling the pore size of a microfiltration membrane by varying the degree of flocculation of the suspensions which are used to film-coat the membranes. The microfiltration membranes are film-coated from an alumina suspension on a porous alumina substrate (capiltary action of the pores is suppressed).
