Novel crystalline silicates which in dehydrated form having the composition in terms of moles of the oxides: (1.0+/-0.3) (R)2/nO. [a Fe2O3. b Al2O3. c Ga2O3. y(dSiO2. eGeO2)], wherein R is one or more mono- or bivalent cations and a, b, c, d, e, y and n are as defined hereinafter are disclosed. The thermally stable silicates are suitably employed as extracting agents, drying agents, ion exhange agents, catalysts and catalyst carriers. |
