Claim 8:
9. The process according to claim 1, wherein the silicon dioxide granulate comprises at least one of the following:
a mean particle size in a range from 50 to 500 μm;
a bulk density in a range from 0.5 to 1.2 g/cm3;
a carbon content of less than 50 ppm;
an aluminium content of less than 200 ppb;
a tamped density in a range from 0.7 to 1.3 g/cm3;
a pore volume in a range from 0.1 to 2.5 mL/g;
an angle of repose in a range from 23 to 26°;
a particle size distribution D10 in a range from 50 to 150 μm;
a particle size distribution D50 in a range from 150 to 300 μm; and
a particle size distribution D90 in a range from 250 to 620 μm,, wherein the wt.-%, ppm and ppb are each based on the total weight of the silicon dioxide granulate.
