A method and apparatus for making silica soot by vapor oxidation |
| abstract |
The present invention relates to a method and apparatus for making a silica soot particle optionally doped. Preferably the method is substantially free of the step of combusting a fuel and substantially free of the step of forming a plasma. Preferably, the apparatus is devoid of a heating element associated with both combustion and formation of a plasma. A preferred technique for at least one heating step for forming the soot particle is induction heating. In general terms, the method and apparatus for coming out the method avoid introducing water (H2, OH, H2O) into the silica particles or deposit and can be used to manufacture preforms for optical fibers. |
