<p>A free-standing ceramic membrane having pores of substantially uniform size can be formed by partly sintering a cast layer of ceramic particles including more than 60 % of larger particles and up to 40 % of smaller particles as a sintering aid. A composite membrane comprises as a support layer the free-standing ceramic membrane, and an overlying film of partly sintered ceramic particles. Both the support layer and the overlying films may be formed by tape casting dispersions of the particles in solutions of polymeric binder in preferably different volatile liquids.</p> |
