摘要： A method and apparatus for maintaining the pressure in an overclad tube at a reduced level despite axial movement of the tube during performance of an RIT overcladding operation. The overcladding tube is held by means of the lathe chuck, and a tubular extension of a rotary union member extends into the tube. The distal end of the extension has a sealing member replaceably mounted thereon which forms a seal with the interior wall of the tube. A vacuum source thus is enabled to connect to the interior of the overcladding tube through the rotary union, the extension tube, and the seal.

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, depositing a first fraction of the glass soot particles on a deposition surface to form a supported soot layer, electrostatically attracting and collecting a second fraction of the glass soot particles onto a surface of a charged plate, removing the soot layer from the deposition surface to form a soot sheet, and heating at least a portion of the soot sheet to sinter the glass soot particles to form a glass sheet.

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 gas phase process for the production of titanium dioxide powders having well-controlled crystalline and surface area characteristics is disclosed. In this process, which is preferably carried out in a laminar diffusion flame reactor, vapor phase TiCl.sub.4 and oxygen are mixed in a reaction area which is heated externally. The titanium dioxide powder formed is then collected. It is preferred that the heat source used be a hydrocarbon fueled (e.g., methane) flame. Optionally, a vapor phase dopant (such as SiCl.sub.4) may be added to the reaction mixture to desirably affect the physical properties of the titanium dioxide produced. In a particularly preferred embodiment, a corona electric field is positioned across the area where the combustion reaction takes place (i.e., the reaction area). High anatase, high surface area titanium dioxide powders made by this process are excellent photocatalysts. The products of this process and the use of those products as photocatalysts are also disclosed. This process is also useful for producing other ceramic powders (such as silicon dioxide and tin oxide), as well as pure metallic or alloy powders.
