Method For Fabrication Of Glass Preform
Abstract: The present disclosure provides a method for fabrication of a glass preform (130). The method includes production of soot particles (116) in a combustion chamber (106) using a precursor material. The heating of the precursor material produces the soot particles (116) along with one or more impurities. In addition, the method includes agglomeration of the soot particles (116). Further, the method includes separation of the soot particles (116) from the one or more impurities. Also, the separation of the soot particles (116) is performed in a cyclone separator (112). Furthermore, the method includes collection of the soot particles (116). Also, the soot particles (116) are compacted with facilitation of a preform compaction chamber (120). Also, the compacted preform (124) is sintered with facilitation of a sintering furnace (130). The compaction of the soot particles (116) followed by sintering results in formation of the glass preform (128).
