    • The disclosed simple economical and rapid sol-gel process for forming a silica-based glass body, termed the "vapogel" process, comprises introduction of a silicon halide-containing gas (eg., SiCl₄ + O₂) into an aqueous medium. The thus formed sol can gel within minutes, resulting in a monolithic gel body. This gel body can be dried and consolidated into a glass body or, preferably, be partitioned into particles having a relatively narrow size distribution. The thus formed particles can be used to produce a glass body such as an optical fiber preform, from which fiber can be drawn. Various techniques for forming the glass body from the gel are disclosed. Among the many advantages of the vapogel method are its ability to produce very homogeneous mixed oxide glasses of composition not obtainable by prior art sol-gel processes, and the advantageous mechanical properties of the gel produced by the method. The latter makes possible, inter alia, formation of particles having a relatively narrow size distribution.
    • 盘简单游离缺失经济且快速的溶胶 - 凝胶法形成的二氧化硅系玻璃体,称为“气凝胶”的过程,包括引入硅含卤化物的气体(例如,四氯化硅+ O2)的成wässrige平台。 由此形成的溶胶凝胶可以在几分钟内,在一个单片凝胶体所得到的。 这种凝胶体可被干燥并合并成一个玻璃体,或优选,被划分成具有一个相对窄的尺寸分布的颗粒。 这样形成的颗粒可用于生产玻璃体:如在光纤预制件,从该纤维可以得出。 从凝胶形成玻璃体的各种技术是游离缺失盘。 之间的气凝胶方法的许多优点是它能够产生的不是由现有技术的溶胶 - 凝胶方法获得的组合物非常均匀的混合氧化物玻璃的能力,以及由该方法制备的凝胶的有利的机械性能。 后期成为可能,除其他外,形成具有相对窄的粒度分布的颗粒。
