Abstract of the Disclosure The object of the present invention is to prepare a dried aluminum hydroxide gel featuring excellent acid neutrizing capacity, but which is also stable. A dried aluminum hydroxide gel with a chemical composition represented by the following general formulas: (M2O)xAl2O3(CO2)yRz?mH2O or [(M2O)x1(CaO)x2(MgO)x3]Al2O3(CO2)yRz?mH2O (wherein M is a monovalent alkali metal and R is an organic acid with a valence of two or more. As a result of its organic acid content, the gel is stable and can have a greater aluminum content, thus improving the acid neutrizing capacity of the gel.
