摘要：
Field
This disclosure is directed to tailoring and improving the expansivity of low thermal expansion silica-titania glass through changes in the [OH] content and fictive temperature of the glasses. The [OH] concentration in the glass can be in the range of 600-2500ppm. The fictive temperature, T F is less than 900°C.
