Abstract
There is disclosed a natural phyllosilicate and, in solid solution therewith, at least one additional silicate or spinel phase such as beta-quartz, beta-spodumene, biotite, donathite, magnetite and Ca.sub.2 MgFe.sub.2 O.sub.6. There is also disclosed a method of producing such solid solution by introducing a phyllosilicate into a salt bath to effect an ion exchange between the salt of the bath and the phyllosilicate and subjecting the ion-exchanged phyllosilicate to a thermal treatment to develop a new phase which forms a solid solution.
