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.
