摘要： Methods for producing localized crystallization in a glass article may include depositing a nucleation catalyst onto at least a portion of a surface of the glass article to form an at least partially coated surface. The nucleation catalyst may be in a solution or in a slurry. The method may include heating the glass article to a nucleation temperature and holding the glass article at the nucleation temperature to form a locally crystallized glass article comprising a crystalline phase and a non-crystalline phase. One or more portions of the locally crystallized glass article adjacent to the nucleation catalyst may include the crystalline phase and a remainder of the locally crystallized glass article may include the non-crystalline phase. The method may also include cooling the locally crystallized glass article.

摘要： A process for manufacturing glass articles from powder at low temperatures includes the steps of preparing a slurry of powder suspended in a liquid; depositing the slurry on a substrate; drying the slurry to form a layer on the substrate; depositing slurry on the layer; drying the slurry deposited on the layer on the substrate to form another layer; repeating the steps of depositing a slurry and drying the to form a plurality of sequential layers on the substrate; and consolidating the plurality of sequential layers to form a glass article. The process requires a small manufacturing footprint, and facilitates the manufacture of very large near-net shape glass articles.

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. The bait substrate is coated with the release coating in a first deposition apparatus and transferred to a second deposition apparatus where the porous soot is deposited, so that release material does not contaminate the soot deposition apparatus.
摘要翻译：一种形成多孔烟灰体的方法，其包括在由诱饵基底支撑的剥离涂层上沉积烟灰。释放涂层的特征控制多孔烟炱体与诱饵基底的连接强度。多孔烟炱体与诱饵底物的弱附着有利于将多孔烟炱体与诱饵基质分离，而不损害多孔烟炱体。剥离涂层可以由脆性材料或在形成多孔烟灰体的烟灰沉积期间氧化或以其他方式消耗的材料形成。脱模涂层可以包括碳。分离的多孔烟灰体可以被固结以形成芯棒，或者可以在烟囱纤维预制棒制造过程中用作套筒（多孔包层）。诱饵基材在第一沉积设备中涂覆有释放涂层，并转移到沉积多孔烟炱的第二沉积设备，使得释放材料不会污染烟炱沉积设备。
