Page 101 - ... Anhydrous Silicates The classification here adopted for the anhydrous silicates cannot be carried through strictly, since there are many species which do not conform to any one of the groups named, and often the true interpretation of the composition is doubtful. Furthermore, within a single group there may be a wide variation in the proportion of the acidic element. I. Disilicates. Salts of Disilicic Acid. RSi2O5. Poly silicates. Salts of Polysilicic Acid.
