摘要： Methods and apparatuses for vaporizing liquid precursor material for use in a vapor deposition process are disclosed. The method for vaporizing liquid precursor material includes introducing a flow of liquid precursor material into an expansion chamber and directing the flow of liquid precursor material towards a wall of the chamber. The wall of the chamber is heated to a temperature sufficient to vaporize a first portion of the flow of liquid precursor material while a second portion of the flow of liquid precursor material remains in a liquid state and a third portion of the liquid precursor material is formed into gel. The expansion chamber is continuously drained as the flow of liquid precursor material is introduced into the expansion chamber. The chamber is heated to a temperature to produce a sufficient amount of the second portion of the liquid precursor material to flush the gel from the chamber.

摘要： A high-surface quality glass sheet is formed using a roll-to-roll glass soot deposition and sintering process. The glass sheet formation involves providing glass soot particles (150), depositing a first fraction of the glass soot particles on a deposition surface (122) to form a supported soot layer (152), electrostatically attracting and collecting a second fraction of the glass soot particles onto a surface of a charged plate with soot gatherng device (125), removing the soot layer from the deposition surface to form a soot sheet (154), and heating at least a portion of the soot sheet to sinter the glass soot particles to form a glass sheet.

摘要： A method for forming an optical quality glass is provided. The method includes contacting silica soot particles with a basic additive, like an ammonia salt, a sodium salt, a potassium salt or a gas, to increase the pH of the silica soot particles to at least 7, forming a silica soot compact, and removing the basic additive from the silica soot compact, e.g. by heating. A method of forming a cladding portion of an optical fiber preform is also provided.
