X - Ray Photoelectron Spectroscopy of Silicate Glasses
X-ray photoelectron spectroscopy (XPS) is a powerful technique capable of providing unique information about the structural chemistry of glasses. However, inappropriate procedures for the preparation of sample surfaces or the lack of reliable methods to overcome electrostatic charging effects during analysis of dielectric materials can cause spurious features to be introduced or intrinsic featu...
متن کاملCorrelation between dielectric constant and chemical structure of sodium silicate glasses
The chemical structure of sodium aluminosilicate glasses is determined by high resolution x-ray photoelectron spectroscopy ~XPS! as silicon is gradually replaced by aluminum. A well-defined chemical state is found for silicon, aluminum, and sodium atoms, while three different environments are identified for oxygen atoms corresponding to Si–O–Si, Si–O–Al, and Si–O–Na bonds. The binding energy of...
متن کاملHigh-pressure radiative conductivity of dense silicate glasses with potential implications for dark magmas.
The possible presence of dense magmas at Earth's core-mantle boundary is expected to substantially affect the dynamics and thermal evolution of Earth's interior. However, the thermal transport properties of silicate melts under relevant high-pressure conditions are poorly understood. Here we report in situ high-pressure optical absorption and synchrotron Mössbauer spectroscopic measurements of ...
متن کاملVerification of the " Tg-A Rule" in Potassium Silicate and Sodium Tungstate Glasses *
A linear relationship exists in oxide glasses between glass transition temperature (Tg) and quadrupole splitting ( A ) of Fe , + . DTA and Mössbauer measurements of silicate and tungstate glasses yielded large slopes of 680 and 260 °C/(mm s~ 1 ) f rom the slope of the straight lines when Fe + occupied, as network former (NWF), distorted tetrahedral Si and distorted octahedral W 6 + sites, respe...
متن کاملStress-corrosion mechanisms in silicate glasses
The present review is intended to revisit the advances and debates in the comprehension of the mechanisms of subcritical crack propagation in silicate glasses almost a century after its initial developments. Glass has inspired the initial insights of Griffith into the origin of brittleness and the ensuing development of modern fracture mechanics. Yet, through the decades the real nature of the ...
