摘要
GeO//2 gel and gels in the SiO//2-GeO//2 system synthesized by the hydrolytic polycondensation of metal alkoxides have been studied by infrared and Raman spectroscopic techniques. The molecular structures, hydroxyl contents, and crystallinity of gels and gel-glasses in relation to the thermal history and GeO//2 concentration were investigated. The binary compositions having up to 70 mol% GeO//2 were examined.
