Abstract: Ultralow expansion titania-silica glass. The glass has high hydroxyl content and optionally include one or more dopants. Representative optional dopants include boron, alkali elements, alkaline earth elements or metals such as Nb, Ta, Al, Mn, Sn Cu and Sn. The glass is prepared by a process that includes steam consolidation to increase the hydroxyl content. The high hydroxyl content or combination of dopant(s) and high hydroxyl content lowers the fictive temperature of the glass to provide a glass having a very low coefficient of thermal expansion (CTE), low fictive temperature (Tf), and low expansivity slope.

Abstract translation: 超低膨胀二氧化钛 - 二氧化硅玻璃。 玻璃具有高羟基含量，并且任选地包括一种或多种掺杂剂。 代表性的可选掺杂剂包括硼，碱元素，碱土金属元素或诸如Nb，Ta，Al，Mn，Sn Cu和Sn的金属。 玻璃通过包括蒸汽固结以增加羟基含量的方法制备。 高羟基含量或掺杂剂和高羟基含量的组合降低了玻璃的假想温度，以提供具有非常低的热膨胀系数（CTE），低假想温度（Tf）和低膨胀斜率的玻璃。
