Zusammenfassung:The significance and implications of gel preparation procedures in controlling the homogeneity of multicomponent oxide gels are discussed. The role of physicochemical factors such as the structure and chemical reactivities of alkoxides, the formation of double-metal alkoxides, and the nature of solvent(s) are critically analyzed in the context of homogeneity of gels during gelation. Three procedures for preparing gels in the SiO 2B 2O 3Na 2O system are examined in the context of cation distribution. Light scattering results for glasses in the SiO 2B 2O 3Na 2O system prepared by both the gel technique and the conventional technique are examined.
