摘要： A process produces a glass overcladding tube from a silica gel body. The process includes passing the gel body through a hot zone under conditions that cause partial sintering of the gel body and repassing the gel body through the hot zone under conditions that further sinter the gel body into a glass overcladding tube.

摘要： A process deals with gaseous by-products and tarry materials during formation of sol-gel bodies. Gaseous products from a dehydroxylation reactor pass into a gas-fluid contactor. During the early stages of heat treatment, an aqueous acid solution is recirculated through the contactor to trap basic and/or water soluble organic gaseous materials. The resultant solution and non-condensing gases pass into a reservoir. Volatile, undissolved organics exit from the reservoir with non-condensing reactor gases and are treated. Once the organics have burned out of the sol-gel body, recirculation of the aqueous acid solution is ceased, and the gas-fluid contactor is flushed. The water flow is then ceased and dry nitrogen is provided to the contactor. During the next stage of the sol-gel heat treatment, gaseous products from the dehydroxylation reactor pass through the contactor into the caustic scrubber. Once the heat treatment is complete, the contactor is flushed.
摘要翻译：一个过程在溶胶凝胶体形成期间处理气态副产物和焦油物质。来自脱羟基化反应器的气态产物进入气液接触器。在热处理的早期阶段，酸性水溶液通过接触器再循环以捕集碱性和/或水溶性有机气态物质。所得溶液和非冷凝气体进入储存器。挥发性，未溶解的有机物从具有非冷凝反应器气体的储层中排出并进行处理。一旦有机物从溶胶 - 凝胶体中烧掉，酸性水溶液的再循环停止，并且气体 - 流体接触器被冲洗。然后停止水流，向接触器提供干燥的氮气。在溶胶 - 凝胶热处理的下一阶段，来自脱羟基反应器的气态产物通过接触器进入苛性碱洗涤器。一旦热处理完成，接触器就会被冲洗掉。

摘要： The invention involves fabricating a ceramic tube, e.g., a silica overcladding tube, with very little bow, e.g., about 0.3 mm per meter or less. In particular, the invention involves securing the tube by a handle that both allows the tube to hang plumb during treatment, and also is capable of deforming during such heat treatment to maintain the plumb arrangement.
摘要翻译：本发明涉及制造陶瓷管，例如二氧化硅外包管，具有非常小的弓，例如约0.3mm /米或更少。特别地，本发明涉及通过手柄来固定管子，两者都允许管子在治疗期间悬挂铅垂，并且还能够在这种热处理期间变形以维持铅垂排列。
