Durability of oxide tellurite glasses Fig. (7.23) shows optical micrographs of glass MOD009 (77TeO2-12ZnO-10Na2O- 1Yb2O3 mol. %) before, and after 60, 120, and 180 sec. immersion in a 1M solution of NaOH at 21°C (see section 7.1.2.1 for further experimental details).
7. Surface properties; MDO 290 20 µm Glass (a) Before (b) 60 sec. (c) 120 sec. (d) 180 sec. Fig. (7.23): Optical micrographs of glass MOD009 (77TeO2-12ZnO-10Na2O-1Yb2O3 mol. %) (a) before, and after (b) 60, (c) 120, and (d) 180 sec. immersion in a 1M solution of NaOH at 21°C (all micrographs the same scale). It can be seen that the surface quality progressively deteriorated, with etch time, indicating NaOH was an unsuitable etchant. After 180 sec., it can be seen that the layer which formed at the surface of the glass began to break up, exposing glass beneath. It can also be seen from the 60 and 120 sec. micrographs that the glass exhibited ridges and pits, indicating the NaOH had attacked the glass incongruently. Fig. (7.24) shows the etch rate
