Abstract
A process for forming a porous inorganic membrane on a porous support is provided. The support is coated with refractory particles which sinter at a first temperature. The coating then is impregnated with an inorganic binder which reacts at a second temperature, lower than the first temperature. The impregnated, coated support then is processed at a temperature at least as high as the second temperature, but less than the first temperature.
