PURPOSE: To obtain a crystalline material adequate for catalysts, etc., by mixing an Si or Ge oxide, water, tetraethyl ammonium compd., a specific metal compd. and cation at prescribed molar ratios and bringing the mixture into reaction under aq. alkaline conditions. n CONSTITUTION: (A) The YO 2 (Y is Si, Ge), (B) the water, (C) the tetraethyl ammonium hydroxide or halide (precursor, reaction product), (D) the feedstock of the X oxide (X is Al, B, Ga, Zn, Fe and Ti) and (E) the feed stock of M(OH)a (M is the cation of valance (a)) are brought into reaction under the aq. alkaline conditions. The mixture of the compsn. consisting of the component A/the component D = at least 5, H 2 O/the component A=4 to 500, OH - /H 2 O=<0.04, the component C/the component A=0.005 to 2 is obtd. The mixture is then crystallized, by which the crystalline material having the compsn. of the formula ((m) is 0.5 to 1.5; (z) is 1 to 2; (y) is ≥5) in a dewatering type and having the X-ray diffraction pattern inclusive of the peaks shown in Table in a fired hydrogen type is obtd. n COPYRIGHT: (C)1990,JPO |
