IPC: C03B19/12
Filed: 1988-08-29
Abstract: PURPOSE:To obtain a large-sized lumpy glass free from cracks and excellent in optical uniformity by processing a wet gel or the dry gel therefrom followed by sintering to effect elimination of the partial difference in shrinkage when heat-treated. CONSTITUTION:A mixture comprising a metal alkoxide, ethanol, water and ammonia water is agitated and left at rest to allow particles to be grown and aged. The resultant system is then concentrated under reduced pressure to prepare a dispersion of fine particles of metal oxide. Thence, this dispersion is mixed with a solution prepared by adding a hydrochloric acid aqueous solution to metal alkoxide and making a hydrolysis under agitation. The resultant system is then incorporated with ammonia water to obtain a liquid gel of the objective glass component composition. This sol is then poured into a closed vessel of desired shape and allowed to be gelled. Thence, the resultant wet gel is either processed and dried or directly dried, and the resulting dry gel is processed to eliminate the fraction of higher particle concentration through spontaneous sedimentation of metallic oxide particles, followed by sintering.
