ABSTRACT:
A porous ceramic laminate has a porous silicon nitride substrate and a porous silicon nitride separation film supported thereon and having minute pores of sizes capable of Knudsen separation or molecular sieve by sintering a porous silicon nitride substrate supporting a formed layer containing polysilazane at 800° C. in a nitrogen atmosphere.
