Stefanovsky, D.V. Semenova, O.I. Stefanovskaya ANNOTATION: The phase composition of sodium-aluminum-phosphate glasses containing rare earth (RE = lanthanum, cerium, europium, and gadolinium) oxides produced by melt quenching and slow cooling, the structure and hydrolytic durability of glasses were determined. Incorporation of up to ~5 wt.% RE oxides does not cause their devitrification during the quenching (with the exception of La-containing glass) and has no significant effect on their structure and hydrolytic stability. After annealing the glasses on the sodium-aluminophosphate basis are subject to devitrification with segregation of sodium-aluminophosphate, RE- (monazite) and sodium RE-phosphate phases. Keywords: hydrolytic durability, infrared spectroscopy, leaching, rare earth elements, sodium-aluminophosphate glass, X-ray diffraction. DOWNLOAD (EN) » DOWNLOAD (RU) » Stefanovsky S.
