Zusammenfassung:Magnesium aluminosilicate, silicic acid of which is not absorbed through digestive tracts on administration, can be produced by reacting polymeric sodium silicate having a siloxane structure of a polymerization degree of 102 to 104 with sodium aluminate in an atomic ratio of Al to Si of 1 - 2 : 1 and then reacting the reaction mixture with a water soluble magnesium salt in an atomic ratio of Mg to Al of 0.5 - 1 : 1.
