Abstract
The most advanced applications of clays depend crucially on their hydration state and swelling is probably the most important feature of expandable 2:1 layered silicates. Sodium Taeniolite, Na-TAE, a swelling trioctahedral fluormica, has been synthesized and studied using thermogravimetric analysis, X-ray diffraction, scanning electron microscopy and infrared and solid state NMR spectroscopies. The results indicated the formation of a swelling 2:1 phyllosilicate with heteroatoms distribution compatible with Li0.95Na0.53[Si8][Mg4.52Li1.48]O20F4·2.16H2O formula which deviates considerably from the usually quoted ideal composition Na2[Si8][Mg4Li2]O20F4·2.16H2O.163
