Abstract:
There is disclosed a fluorinated phyllosilicate material and method of producing such material. The material has fluoride ions chemically bonded to a natural phyllosilicate in part at least by exchange with hydroxyl ions. The method comprises exposing a phyllosilicate to a source of fluoride ions, either gaseous, aqueous fluoride solution, or a volatile solid, and chemically bonding flouride ions to the phyllosilicate structure. The fluorinated material may be heated to a temperature in the range of 100.degree.-1000.degree. C., preferably 300.degree.-800.degree. C. to dehydrate the material. Heating at 800.degree. C. may create new crystal phases, such as sellaite (MgF.sub.2) or fluorite (CaF.sub.2).

Abstract:
Sodium zinco/stanno/titano-silicate is synthesized by mixing a concentrated aqueous sodium zincate, stannate or titanate solution with a source of silica (e.g. powdered glass or sodium metasilicate solution) in the ratio 60 g sodium silicate to sodium zincate equivalent to 8.1 g zinc oxide, keeping the temperature at 40.degree. C. for 1/2 hour, diluting threefold with water of 20.degree. C., allowing a precipitate to form overnight, and filtering and drying the residue at 110.degree.
