PREPARATION OF A COMPOSITION OF A SWELLING T.O.T.-T.O.T. INTERLAYER |
摘要 |
A method for preparing a composition including mineral particles, that is swelling TOT-TOT interlayer particles, formed by interlayering between: at least one non-swelling mineral phase formed by a stack of elementary laminae of the phyllogermanosilicate 2/1 type and of formula —(SixGe1−x) 4M3O10(OH)2—, and at least one swelling mineral phase formed by a stack of elementary laminae of the phyllogermanosilicate 2/1 type and at least one interlaminar space between two consecutive elementary laminae, the swelling mineral phase being of formula —(SixGe1−x)4M3−&egr;O10(OH)2, (M2+)&egr;′.nH2O. The composition is prepared by subjecting a gel containing silicon, germanium and metal, of chemical formula —(SixGe1−x)4M3O11,nH2O—, in the liquid state to a hydrothermal treatment which is carried out over a defined period of time and at a temperature of between 150° C. and 300° C., the time and temperature being selected according to the desired structural characteristics for the swelling TOT-TOT interlayer particles to be prepared. |
