A method for making silica, comprising:
- delivering a silica precursor comprising a pseudohalogen to a conversion site;
- and
- passing the silica precursor through a flame to produce silica soot.
A method for making germania-doped silica comprising:
- delivering a silica precursor comprising a pseudohalogen and a germania precursor comprising a pseudohalogen to a conversion site;
- and
- passing the silica precursor and the germania precursor through a flame to produce the germania-doped silica.
A method for making silica, comprising:
- delivering a silica precursor comprising a pseudohalogen and an oxidant inside a heated tube to form silica;
- and
- depositing the silica on an inner surface of the tube.
A method for making fused silica, comprising:
- delivering a silica precursor comprising a pseudohalogen to a conversion site;
- passing the silica precursor through a flame to produce silica soot;
- and
- depositing the silica soot onto a deposition surface, wherein the silica soot is immediately consolidated into glass.
