23410-224RABSTRACTSodium zinco/stanno/titano-silicate is synthesized by mixinga concentrated aqueous sodium zincate (stannate, titanate) solution with asource of silica (e.g. powdered glass or sodium metasilicate solution) in theratio 60g sodium silicate to sodium zincate equivalent to 8.1g zinc oxide,keeping the temperature at 40°C for 1/2 hour, diluting threefold with waterof 20°C, allowing a precipitate to form overnight, and filtering and dryingthe residue at 110°C. The resulting sodium zincosilicate may be used in itsown right as a water softener or may be converted by cation exchange into anyother desired zincosilicate.
