A porous inorganic membrane for use with a membrane device having a porous support, the membrane including refractory particles bound to each other and to the support by a thermally reactive inorganic binder which reacts at a temperature below that at which the refractory particles react. Further, a method of forming a porous inorganic membrane on a support by applying a coating of a mixture of refractory particles and a thermally reactive inorganic binder to the support. The inorganic binder reacts at a first temperature lower than a second temperature at which the refractory particles sinter. The method further includes firing the support to a firing temperature at least as high as the first temperature and less than the second temperature to react the inorganic binder, and cooling the support to form the porous membrane. |
