Abstract
A synthetic film including a porous; the alumina substrate containing more than 90 wt % of alumina pores in the alumina substrate have a mean diameter of 0.1.about.3.0 .mu.m. A zeolite crystal body is formed in the pores and on the substrate. The synthetic film is manufactured by preparing the alumina substrate, immersing the substrate in a slurry containing zeolite crystal and its precursor prepared from a silica source using sodium silicate or water glass, and subjecting the substrate with slurry to a hydrothermal crystallization at least one.
