Abstract
A process for producing a glass body, the process including flowing oxygen gas from a burner in a furnace at a flow rate of greater than 12.0 standard liters per minute and flowing a precursor gas mixture from the burner. The process further including oxidizing the precursor gas mixture with the oxygen gas to form glass particles and depositing the glass particles on a collection cup to form the glass body.
Claims15
A process for producing a glass body, the process comprising:
- flowing oxygen gas from a burner in a furnace at a flow rate in a range of about 12.0 standard liters per minute to about 15.6 standard liters per minute;
- flowing a precursor gas mixture from the burner at a flow rate of less than 5.1 grams/minute, the precursor gas mixture comprising a silicon-containing precursor and a titanium-containing precursor;
- oxidizing the precursor gas mixture with the oxygen gas to form glass particles;
- and
- depositing the glass particles on a collection cup to form the glass body,
- wherein the glass body comprises a titanium content in a range of about 1 wt. % to about 10 wt. %.
