Abstract

PURPOSE:To avoid cracking and deforming in a sintering step and enable vitrification in high yield, by previously subjecting a dried gel to dehydration treatment at a low temperature in a chlorine based gas atmosphere and sintering the gel in producing glass by a sol-gel method. CONSTITUTION:Glass is produced by a sol-gel method. In the process, a dried gel is subjected to dehydration treatment at a low temperature in a chlorine based gas atmosphere, then thermally sintered and vitrified. OCl4 or SOCl2 can be used as the chlorine based gas in addition to chlorine gas. The dehydration treatment at the low temperature is preferably carried out under condition of a temperature within the range of ordinary temperature -100 deg.C for >=1hr treating time.
