Abstract

Effects of heat-treatment (1250°C, 150 min) on the structure of high pure silica glass samples treated with different degree of polishing and containing different OH content have been investigated by SAXS technique. An abrupt increase of SAXS intensity from the surface layer was observed after heat-treatment. Samples polished with coarse grain powder, SiC#320 mesh, showed higher SAXS intensity than samples polished with SiC#800 mesh. Furthermore, it is shown that OH content in silica glass affects in SAXS intensity. These two effects: polishing degree and OH content in the structure after heat-treatment are discussed in terms of SAXS and higher angle scattering intensity.
