Partitioning of gadolinium and its induced phase separation in sodium-aluminoborosilicate glasses

Abstract

Phase separation in sodium-aluminoborosilicate glasses was systematically studied as a function of Gd2O3 concentration with transmission electroni microscopty (TEM), energy dispersive X-ray spectroscopy (EDS) and electroni energy loss spectroscopy (EELS) methods. Dissolving Gd2O3 in sodium-aluminoborosilicate glasses causes phase separation when the Na2O/(Na2O + Al2O3) is between 0.4 and 0.6. Samples of these glasses were examined in the TEM with ELFS. The results are reported.
