Abstract
A method of forming a doped silica-titania glass is provided. The method includes blending batch materials comprising silica, titania, and at least one dopant. The method also includes heating the batch materials to form a glass melt. The method further includes consolidating the glass melt to form a glass article, and annealing the glass article.
Claims11
A method of forming a doped silica-titania glass, the method comprising:
- blending batch materials comprising silica, titania, and at least one dopant, the silica and titania having fine particle size, and the at least one dopant being one of a material with fine particle size and a dopant precursor gas, wherein the batch materials comprise titania having a particle size of between about 0.01 μm and about 0.10 μm;
- heating the batch materials to form a glass melt;
- consolidating the glass melt to form a glass article;
- and
- annealing the glass article.
