摘要： A method of melting glass and glass-ceramics that includes the steps: conveying a batch of raw materials into a submerged combustion melting apparatus, the melting apparatus having liquid-cooled walls and a floor; directing a flame into the batch of raw materials and the melted batch with sufficient energy to form the raw materials into the melted batch; and heating a delivery orifice assembly in the floor of the submerged melting apparatus to convey the melted batch through the orifice assembly into a containment vessel. The melted batch has a glass or glass-ceramic composition that is substantially reactive to a refractory material comprising one or more of silica, zirconia, alumina, platinum and platinum alloys.

摘要： A method and apparatus for making an optical fiber preform. The apparatus has an outer wall and an inner wall. The outer wall surrounds the inner wall and the inner wall surrounds an inner cavity of the apparatus. A core rod is deposited in the inner cavity after which particulate glass material, such as glass soot, is deposited in the inner cavity around the core rod. The core rod has at least 10 percent of the final cladding soot already applied thereto. A radially inward pressure is applied against the particulate glass material to pressurize the particulate glass material against the core rod.

摘要： A method of preparing an optical preform includes the steps of: a) etching an optical preform to remove a portion of an oxide material deposited on the preform by using a gas comprising an etchant gas containing fluorine at a sufficient temperature and gas concentration to create a redeposited germanium containing compounds contamination such as GeOx in the remaining oxide material; and b) cleaning the etched preform using a cleaning gas containing at least one halogen gas at a sufficient temperature and gas concentration to remove the redeposited germanium containing compound contamination without any substantial further contamination of the remaining deposited oxide material. Preferably the halogen is either chlorine or bromine.

摘要： A fused silica article having a combined concentration of hydroxyl (OH) and deuteroxyl (OD) concentration of less than 10 parts per million (ppm) and, in one embodiment, less than 1 ppm. The fused silica article is formed by drying a soot blank in a halogen-free atmosphere comprising carbon monoxide. The dried soot blank may optionally be doped to reach target levels of OH and OD concentrations and improve homogeneity within the fused silica article. The dried soot blank is then oxidized and sintered to form the article. A method of reducing the combined concentration of OH and OD to less than 10 ppm is also described.
