US 10,570,048 B2 · Silica-containing sheet and related system and methods

Abstract

A system and process for making a thin, soot particle or glass sheet is provided. The system includes a soot deposition plate having a deposition surface and a glass soot generating device spaced from the deposition surface along a first axis. The glass soot generating device is configured to generate glass soot particles and to deliver the glass soot particles through an outlet and on to the deposition surface in a layer having a thickness of less than 5 mm. At least one of the soot deposition plate and the glass soot generating device is movable to cause relative movement between the deposition surface of the soot deposition plate and the glass soot generating device. A thin soot or sintered soot sheet is also provided. The soot sheet has a variable surface topography that varies along at least two axes.

Dependent claims

A silica-containing sheet comprising:

a first major surface, the first major surface having a variable surface topography;
a second major surface opposite the first major surface;
at least 50 mole % silica;
an average thickness between the first major surface and the second major surface of less than 5 mm;
a length of at least 1 cm and a width of at least 1 cm;
wherein the variable surface topography of the first major surface varies having at least two layers that are not coplanar with each other such that:
a first surface profile along a first x-axis is different than a second surface profile along a second x-axis;
and
a third surface profile along a first y-axis is different than a fourth surface profile along a second y-axis.
