Crystalline inclusion compounds of silicon dioxide, method for their preparation, and use |
摘要 |
The invention relates to crystalline inclusion compounds, having a structure analogous to the gas hydrates of structural type II, of silicon dioxide with the formula 136 [(Si1-xTx)O2].(24-y)M, where T is an atom coordinated tetrahedrally by oxygen, x represents a numerical value of </= 0.1, y represents a numerical value of 0 </= y </= 24, and M represents atoms, molecules and/or ions having kinetic diameters according to Lennard-Jones of sigma </= 9 ANGSTROM , and to the method for their preparation by heating alkaline SiO2-containing solutions having SiO2 contents >/= 0.01 M and base: SiO2 ratios between 0.4 : 1 and 20 : 1 at superatmospheric pressures to temperatures above 120 DEG C, and to their use as agents for absorbing and storing atoms, molecules and/or ions having kinetic diameters according to Lennard-Jones of sigma </= 9 ANGSTROM . |
