Process for preparation of alkaline earth metal aluminosilicate sintered body.

摘要

A process for the preparation of an alkaline earth metal aluminosilicate sintered body, which comprises molding a mixture comprising (a) a zeolite of an alkaline earth metal form having an SiO2/Al2O3 molar ratio not higher than 3.0 or an amorphous calcination product formed by calcining said zeolite and (b) boron oxide or a boron compound capable of being converted to boron oxide by firing, and firing the molded mixture at a temperature lower than 1000 DEG C.
