Abstract
A method for forming a fused silica glass includes delivering a silica precursor to a burner and passing the silica precursor through the flame of the burner to form silica particles, depositing the silica particles on a planar surface to form a flat, porous preform, dehydrating the porous preform, and consolidating the porous preform into a flat, dense glass.
Claims12
A method for forming a fused silica glass, comprising:
- delivering a silica precursor to a burner and passing the silica precursor through the flame of the burner to form silica particles;
- depositing the silica particles on a planar surface to form a flat, porous preform, wherein the temperature of the planar surface is maintained in a range from approximately 600 to 900° C.;
- dehydrating the porous preform;
- and
- consolidating the porous preform into a flat, dense glass.

A method for producing a fused silica glass containing titania, comprising:
- delivering a mixture of a silica precursor and a titania precursor to a burner and passing the mixture through the flame of the burner to form SiO2—TiO2 particles;
- depositing the SiO2—TiO2 particles on a planar surface to form a flat, porous preform, wherein the temperature of the planar surface is maintained in a range from approximately 500 to 900° C.;
- and
- consolidating the porous preform into a flat, dense glass.
