Abstract
Disclosed are process and apparatus for making high purity fused silica glass materials. The process involves depositing soot particles onto an essentially planar deposition supporting surface and modulation of motion of the soot-generating device relative to the deposition supporting surface to result in a low local soot density variation. The apparatus is designed to implement the planar deposition process. The invention makes it possible to produce fused silica glass without the use of potentially contaminating refractory bricks.
