    Abstract: A porous glass base material manufacturing system that does not require the manufacturing apparatus and building to be hazardous material-compatible and that can provide a stable supply of raw materials, even when organic siloxane raw material is used as raw materials to produce silica fine particles includes a raw material supplying apparatus and a porous glass base material manufacturing apparatus. The raw material supplying apparatus includes: a raw material tank in which organic siloxane raw material in a liquid state is stored and the remaining space is filled with inert gas; a liquid feed pump to pump the organic siloxane raw material from the raw material tank; a circulating piping and a branch piping through which the raw material pumped is passed; a liquid mass flow controller that controls the flow rate of organic siloxane raw material passed through the branch piping to a predetermined flow rate; and a vaporizer.

    Abstract: The present disclosure provides a method for fabrication of a glass preform. The method includes production of soot particles in a combustion chamber using a precursor material. The heating of the precursor material produces the soot particles along with one or more impurities. In addition, the method includes agglomeration of the soot particles. Further, the method includes separation of the soot particles from the one or more impurities. Also, the separation of the soot particles is performed in a cyclone separator. Furthermore, the method includes collection of the soot particles. Also, the soot particles are compacted with facilitation of a preform compaction chamber. Also, the compacted preform is sintered with facilitation of a sintering furnace. The compaction of the soot particles followed by sintering results in formation of the glass preform.

    Abstract: A system and method for making a thin sintered silica sheet is provided. The method includes providing a soot deposition surface and forming a glass soot sheet by delivering a stream of glass soot particles from a soot generating device to the soot deposition surface. The method includes providing a sintering laser positioned to direct a laser beam onto the soot sheet and forming a sintered glass sheet from the glass soot sheet by delivering a laser beam from the sintering laser onto the glass soot sheet. The sintered glass sheet formed by the laser sintering system or method is thin, has low surfaces roughness and/or low contaminant levels.

    Abstract: A process for the production of a self-supporting glass film is described. The method includes the steps of preparing a mixture containing a colloidal silica sol, at least one alkanolamine organic additive and an organic binder; coating the mixture onto a base material; drying the coated mixture to form a precursor film on the base material; releasing the precursor film from the base material; and firing the released precursor film to form a self-supporting glass film. Self-supporting glass films produced by the disclosed process are also described.
