Depolymerization of Germanium Dioxide Glass by Copper(1) and Copper(I1) Oxides' E. F. RIEBLING
Received April 4, 1973 Copper germanate glasses containing either Cu,O u p to 1 2 mol % or Cu(II):Cu(I) ratios up t o 0.175 (and as little as 70 mol % GeO,) were prepared by allowing Cu,O and GeO, t o react in alumina crucibles in air above l l O O o . Higher Cu,O content binary germanate glasses were not obtained because of (a) CuO formation on heating, (b) incomplete CuO decomposition above 1026" if larger amounts of Cu,O were used, and (c) practical glass-melting considerations above 1000". Small additions of Cu,O (
