    摘要： 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:(M.sub.2 O).sub.x Al.sub.2 O.sub.3 (CO.sub.2).sub.y R.sub.z.mH.sub.2 O or[(M.sub.2 O).sub.x1 (CaO).sub.x2 (MgO).sub.x3 ]Al.sub.2 O.sub.3 (CO.sub.2).sub.y R.sub.z.mH.sub.2 O(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 grater aluminum content, thus improving the acid neutrizing capacity of the gel.
