Abstract
A method and a burner for manufacturing silica-containing soot is disclosed. The method includes providing a liquid silicon-containing feedstock and a gas mixture and ejecting the liquid-gas mixture from an orifice into a combustion site to convert the silica-containing feedstock into silica containing soot. The burner includes a plurality of channels for delivering a gas to provide a flame, an effervescent atomizer for atomizing a liquid, silicon-containing feedstock and a rail for guiding the atomized liquid, silicon-containing feedstock into the burner flame. The method and burner can be used to produce silica-containing articles such as high purity fused silica optical members and waveguides.
