| titleOfInvention | Method for producing optical quality glass |
| abstract | The presintered composition is deposited on a preform that is intended to move in front of a plasma flame that moves back and forth substantially parallel to the longitudinal direction of the preform, to produce glass, and the first feed canal supplies crystals of the presintered composition to the plasma, Optionally, a second feed tube feeds the plasma with a fluorine or chlorine compound, preferably a fluorine compound mixed with the carrier gas, and the presintering composition has a BET surface area of 30 to 90 m 2 / g, a DBP index of 80 or less, 25000 Granules of pyrogenic silicon dioxide powder metal oxide or metalloid oxide having an average aggregate area of less than 2 nm and an average aggregate circumference of less than 1000 nm, wherein at least 70% of the aggregates have a circumference of less than 1300 nm, or flame hydrolysis It has a metal content of less than 0.2 μg / g prepared by reacting silicon tetrachloride having a metal content of less than 30 ppb by It consists of a silicon dioxide prepared in a highly pure pyrogenically. |
