摘要： A method for producing ultra-high purity, optical quality, glass articles is disclosed which involves: 1) forming a gel from a silicon-containing organic compound, such as, TEOS; 2) drying the gel to produce granules having a mean particle size of less than about 1 millimeter; 3) fully sintering the granules to produce high purity, artificial sand; 4) casting the artificial sand by conventional techniques, such as, slip casting, to form a high density, porous, green body; 5) drying and partially sintering the green body; 6) fully sintering the green body under vacuum; and 7) hot isostatic pressing ("hipping") the green body. The glass articles produced by the process have higher purity, greater homogeneity, and less IR absorption than existing, commercially available, premium quality, fused silica, glass articles. In addition, in accordance with the invention, high purity glass articles of complex shapes can be directly cast, rather than being machined or pressed from sheets of glass, as in the prior art.

摘要： A method for forming a porous soot body that includes depositing soot on a release coating supported by a bait substrate. Characteristics of the release coating control the strength of attachment of the porous soot body to the bait substrate. Weak attachment of the porous soot body to the bait substrate facilitates separation of the porous soot body from the bait substrate without damaging the porous soot body. The release coating may be formed from a brittle material or a material that oxidizes or otherwise depletes during deposition of the soot that forms the porous soot body. The release coating may include carbon. The separated porous soot body may be consolidated to form a core cane or may function as a sleeve (porous cladding) in a cane-in-soot fiber preform manufacturing process.
