Abstract:
One aspect relates to a process for the preparation of a quartz glass grain, including providing a silicon dioxide granulate from a pyrogenically produced silicon dioxide powder, making a glass melt out of silicon dioxide granulate, making a quartz glass body out of at least part of the glass melt and reducing the size of the quartz glass body to obtain the quartz glass grain. One aspect further relates to a quartz glass grain which is obtainable by this process. One aspect further relates to opaque quartz glass bodies, which are obtainable by further processing of the quartz glass grain.

Claim (Index 20):
The process according to  claim 15 , wherein the silicon dioxide granulate comprises at least one of:\n a BET surface area in a range from 20 to 50 m 2 /g; a mean particle size in a range from 50 to 500 \u03bcm; a bulk density in a range from 0.5 to 1.2 g/cm 3 ; 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 1.0 g/cm 3 ; 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\u00b0 ; a particle size distribution D 10  in a range from 50 to 150 \u03bcm; a particle size distribution D 50  in a range from 150 to 300 \u03bcm; and a particle size distribution D90 in a range from 250 to 620 \u03bcm, wherein the ppm and ppb are each based on the total weight of the silicon dioxide granulate.
