Structure and bonding in As-Sb-S chalcogenide glasses by infrared reflectance spectroscopy

The structure of chalcogenide glasses xSb//2S//3 center dot (1 minus x)As//2S//3 with 0 less than equivalent to x less than equivalent to 0.75 was studied by infrared reflectance spectroscopy. The absorption coefficient spectra, calculated from reflectance by Kramers-Kronig analysis, were… Read moreStructure and bonding in As-Sb-S chalcogenide glasses by infrared reflectance spectroscopy

Compositional dependence of bioactivity of glasses in the system CaO- B//2O//3-SiO//2: Its in vitro evaluation

The essential condition for glasses and glass-ceramics to bond to living bone is the formation of a biologically active bone-like apatite layer on their surfaces in the body. In the present study, in order to investigate fundamentally the effect of… Read moreCompositional dependence of bioactivity of glasses in the system CaO- B//2O//3-SiO//2: Its in vitro evaluation

Kinetic factors affecting the corrosion of SiO//2 in silicate glasses caused by alkaline solutions

The corrosion of a ZrO//2 containing alkali resistant silicate glass, float glass and silica glass caused by the aqueous solution of NaOH was studied by use of correlation method with spectrophotometry. Effects of the corroding temperature, time and solution concentration… Read moreKinetic factors affecting the corrosion of SiO//2 in silicate glasses caused by alkaline solutions

Investigations into structure and composition of gel layers on medieval window glasses of the Katharinenkirche, Oppenheim (Germany), and the Cathedral St. Gatien, Tours (France)

Optical microscopy, Scanning Electron Microscopy (SEM), X-Ray Diffraction analysis (XRD) and Energy dispersive electron Probe Micro Analysis (EPMA) were used to characterize surface and subsurface layers and areas on medieval church window glasses generated by weathering and contamination, respectively. Investigations… Read moreInvestigations into structure and composition of gel layers on medieval window glasses of the Katharinenkirche, Oppenheim (Germany), and the Cathedral St. Gatien, Tours (France)
