摘      要：SiO 2-GeO 2 sols and gel glass coatings with different contents of germanium dioxide were *** and transparent sols could only be obtained when the content of GeO 2 was under 35%.It is shown by SEM that only one continuous phase is observed in the coating of 65SiO 2·35GeO 2 and plenty of Ge,O and Si were all found in ***,the separated phase is found in the coating of 60SiO 2·40GeO 2 and a large number of Ge and *** is proved by the Raman scattering investigation that the separated phase in the coating of 60SiO 2·40GeO 2 is germanium *** congeries of hydrolystates of Cl 3GeCH 2CH 2COOH play the main role in the formation of the separated phase when the proportion of GeO 2 is much ***-O-Ge,Si-O-Si,and Ge-O-Ge bonds form in the coating of 65SiO 2·35GeO 2 and this coating is homogenous.
