ABSTRACT:
A crystalline hydrated layered sodium and potassium silicate/amorphous sodium and potassium silicate composite material with predetermined hardness ion sequestration properties is achieved by controlling the process for forming the material. The process for producing the crystalline hydrated layered sodium and potassium silicate/amorphous is sodium and potassium silicate composite comprises hydrolyzing DB-1 crystalline sodium and potassium silicate glasses as a precursor material to produce the composite material known as DB-2. Hydrolysis of the DB-1 precursor material is achieved by adding typically up to 100.0 milliequivalents per gram of H.sub.3 O.sup.+ ions or up to 50 milliequivalents per gram of OH.sup.- ions. The resulting DB-2 material can sequester CA.sup.2+ ions, Mg.sup.+ ions, or both, depending on the results desired, processing conditions, and starting materials used.
