Abstract
An improved method for the production of a monolithic multicomponent oxide glass is achieved by forming an oxide host gel by a sol-gel process, placing the host gel in an aqueous solution of a salt of at least one metal selected from the group consisting of Li, Na, K, Rb, Cs, Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Pb, precipitating the metal salt in the gel and sintering the gel containing the precipitated salt. The method can incorporate large amounts of metals into the glass which are otherwise difficult or impossible to incorporate into precursor gels by conventional methods.
