The aim of this study was to investigate the effect of 850°C heat treatment time on LaAlGaB5O24 amorphous xerogel. Structural changes were evidenced by X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. If xerogel remains non-crystalline after 5min treatment, nanocrystallites of LaAl2.03(B4O10)O0.54 type are developed after 15min treatment and this is the sole crystalline...
The structural environment around Y in silicate and aluminosilicate glasses containing 5000ppm Y was investigated as a function of melt composition and polymerization using Extended X-ray Absorption Fine Structure (EXAFS) spectroscopy. The used glass compositions were taken from Prowatke and Klemme (2005) varying in the aluminum saturation index (ASI, molar ratio of Al 2 O 3 /(Na ...
