Title:
METHOD FOR PRODUCING GLASS PARTICULATE DEPOSIT
Document Type and Number:
WIPO Patent Application WO/2019/240232
Kind Code:
A1
Abstract:
A method for producing a glass particulate deposit, said method comprising using siloxane as a starting material for glass, discharging the siloxane gasified in a vaporizer and a combustion gas from a burner and combusting, and thus forming a glass particulate deposit in a reaction vessel, wherein: after producing a good section of the glass particulate deposit, the supply of the siloxane that is the starting material for glass to the burner is ceased while continuously supplying the combustion gas to the burner; then the glass particulate deposit is taken out from the reaction vessel; a starting material gas port from the vaporizer to the burner is purged by flowing an inert gas therethrough; and, when a color derived from the combustion of the siloxane gas is not observed any more in the flame of the burner, then the supply of the combustion gas is ceased.
