HOMOGENOUS SILICA-TITANIA GLASS

A glass comprising titania and silica is disclosed. A plot of average hydroxide concentration of each segment of a plurality of segments vs. distance along the glass is provided by: y = Ax2 + Bx + C, wherein A (in ppm/mm2) is in a range from about 0.0 to about -0.1, B (in ppm/mm) is in a range from...

More Information
Summary:A glass comprising titania and silica is disclosed. A plot of average hydroxide concentration of each segment of a plurality of segments vs. distance along the glass is provided by: y = Ax2 + Bx + C, wherein A (in ppm/mm2) is in a range from about 0.0 to about -0.1, B (in ppm/mm) is in a range from about -10 to about 10, C (in ppm) is about 150 or less, y is the average hydroxide concentration (in ppm), and x is distance (in mm) such that the hydroxide concentration of each segment is measured using a Fourier transform infrared spectroscopy in transmission and the plot extends a distance of about 50 mm or more along the glass.
