Pressure Induced Densification and Compression in a Reprocessed Borosilicate Glass
Pressure induced densification and compression of a reprocessed sample of borosilicate glass has been studied by X-ray radiography and energy dispersive X-ray diffraction using a Paris-Edinburgh (PE) press at a synchrotron X-ray source. The reprocessing of a commercial borosilicate glass was carried out by cyclical melting and cooling. Gold foil pressure markers were used to obtain the sample p...
متن کاملPressure-Induced Densification of Oxide Glasses at the Glass Transition
Densification of oxide glasses at the glass transition offers a novel route to develop bulk glasses with tailored properties for emerging applications. Such densification can be achieved in the technologically relevant pressure regime of up to ~1 GPa. However, the present understanding of the composition–structure–property relationships governing these glasses is limited, with key questions, e....
متن کاملFemtosecond laser-induced stress-free ultra- densification inside porous glass
Unusually high densification ⩽26% was obtained without lateral residual stresses within the laser beam waist inside porous glass during its multi-shot femtosecond laser irradiation, which may induce in the glass the related high refractive index change ~0.1. Corresponding laser irradiation regimes, resulting in such ultra-densification, decompaction and voids inside the glass, were revealed as ...
متن کاملStructure of Rhenium-Containing Sodium Borosilicate Glass
A series of sodium borosilicate glasses were synthesized with KReO4 or Re2O7, to 10,000 ppm (1 mass%) target Re, to assess effects of large concentrations of rhenium on glass structure and fto estimate solubility of Tc, a radioactive component in low active waste nuclear glasses. Rhenium was used as a surrogate for Tc for laboratory testing, due to similarities in chemistry, ionic size, and red...
متن کاملInvestigation of gamma radiation induced changes in local structure of borosilicate glass by TDPAC and EXAFS
Gamma radiation induced changes in local structure around the probe atom (Hafnium) were investigated in sodium barium borosilicate (NBS) glass, used for immobilization of high level liquid waste generated from the reprocessing plant at Trombay, Mumbai. The (NBS) glass was doped with 181Hf as a probe for time differential perturbed angular correlation (TDPAC) spectroscopy studies, while for stud...
