    Abstract: 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.

    Abstract: 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.

    Abstract translation: 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。

    Abstract: One embodiment of the disclosure relates to a method of cleaning silica-based soot or an article made of silica-based soot, the method comprising the step of treating silica-based soot or the article made of silica-based soot with at least one of the following compounds: (i) a mixture of CO and C1 2 in a carrier gas such that the total concentration of CO and C1 2 in the mixture is greater than 10 % (by volume, in carrier gas) and the ratio of CO:C1 2 is between 0.25 and 5; (ii) CC1 4 in a carrier gas, such that concentration CC1 4 is greater than 1 % (by volume, in carrier gas). Preferably, the treatment by CC1 4 is performed at temperatures between 600 °C, and 850 °C. Preferably, the treatment with the CO and Cl mixture is performed at temperatures between 900 °C and 1200 °C. The carrier gas may be, for example, He, Ar, N 2 , or the combination thereof.
