Procedure
A 0.238M solution of sodium fluoride NaF was previously prepared by dissolving 2.5 g of NaF in 250 mL of water. 0.84 mL of this solution was added in the TEOS solution, in order to obtain a molar ratio NaF/TEOS=2.56. Each solution was placed in a shaking bath (shaking speed: 40 rpm) thermostated at either 25° C. (Example 10), 35° C. (Example 11), 45° C. (Example 12), 55° C. (Example 13) or 65° C. (Example 14), for 48 hours). A white suspension appeared progressively. After 48 hours, the powder was separated from solution by centrifugation (5,000 rpm, 10 minutes), dried at 70° C., then calcined in air at 5° C. min-1 to 200° C. for 6 hours, then 600° C. for 6 hours.
