Formation of silica glass
surface defects under heat treatment
Abstract
Some results of electronic
microscope research of the surface of the resonators made from high and small
internal stress silica glass are given. They show if there is internal stress
in silica glass then the heat treatment leads to both decrease the stress and
fast grow surface cracks with depth up to 0.5 mm. The grown of the surface
defects leads to worsen optic and mechanical characteristics of the silica
glass and to internal friction in the surface layer.
