With artificially the pore size in porous, applications as soil filter and heat resistance materials can be taken into consideration. We tried to prepare porous bodies which were composed of β-eucryptite, by simultaneously inducing a foaming reaction between sodium hydroxide and aluminum powder, and a gelling and setting reaction between sodium silicate and sodium aluminate. Then, the dominant factors of the detained structures were investigated. Gelling/setting reactions and foam forming reactions were controlled lay varying the reaction temperature and the amount of aluminum powder, respectively. The factors of foam forming rates and shrinkage rates remarkably depended both on the reaction temperature and the weight rate of aluminate slurries to mixed slurries, respectively. Varying these factors, the pore size was found to be controllable in the range 70÷260μm.
