Description:
The present paper reports the polymeric sponge method of porous ceramic supports from porcelain mixtures. In this work, polyurethane (PU) foam with three different pore sizes have been selected, which are 100 ppi and 120 ppi as a substrate (support) and 10 ppi as an intermediate layer (catalyst support). In addition, the tubular support shape is selected, which its provide mechanical strength to intermediate layer and membrane layer to withstand the stress induced by the pressure applied over the whole supports. Tubular configuration has been produced by polymeric sponge method. The foam with 120 ppi has a positive effect on the porosity ratio of supports compared to those prepared from 100 ppi. Moreover, the influence of the sintering temperature on the total porosity, average pore size and compressive strength of supports has been investigated.
