Silicate Liquids

Properties of liquid silicates under high-pressure and high-temperature conditions are critical for modeling the dynamics and solidification mechanisms of the magma ocean in the early Earth, as well as for constraining entrainment of melts in the mantle and in the present-day core–mantle boundary. Here we present in situ structural measurements by X-ray diffraction of selected amorphous silicates compressed statically in diamond anvil cells (up to 157 GPa at room temperature) or dynamically by laser-generated shock compression (up to 130 GPa and 6,000 K along the MgSiO3glass Hugoniot). The X-ray diffraction patterns of silicate glasses and liquids reveal similar characteristics over a wide pressure and temperature range. Beyond the increase in Si coordination observed at 20 GPa, we find no evidence for major structural changes occurring in the silicate melts studied up to pressures and temperatures exceeding Earth’s core mantle boundary conditions. This result is supported by molecular dynamics calculations. Our findings reinforce the widely used assumption that the silicate glasses studies are appropriate structural analogs for understanding the atomic arrangement of silicate liquids at these high pressures.

Process Simulator

AbstractIn this study, we present a numerical model, implemented in our two-dimensional Finite-Element process simulator, allowing the evaluation of the mechanical stress generated by deposited oxides in case of adsorbing or desorbing of water. Using both in-situ and ex-situ measurements of stress, the model parameters (water diffusion, evaporation rate, viscosity) are calibrated. Moisture instability of doped silicate glasses, like borophosphosilicate (BPSG) and phosphosilicate (PSG), is investigated. Moreover, an extension of the present model to simulate the densification of Spin-On-Glass (SOG) will be demonstrated. A failure analysis of a specific structure in an industrial process will validate the capability of the model to evaluate and minimize the risk of cracking in SOG films during densification.

Before And After

To estimate the ratio of densification to Vickers indentation volume, three-dimensional images of Vickers indentations on several glasses, including silicate glasses and bulk metallic glass (BMG), were obtained before and after annealing using an atomic force microscope. Large volume recovery of Vickers indentation by annealing was observed for all glasses but BMG. Following previous studies, this recovered volume almost corresponded to the densified volume under a Vickers indenter, and the compositional dependence of densification was discussed. The ratios of densification to the total indentation volume for silica and soda-lime glasses were 92% and 61%, respectively. It was concluded that densification was a general property for silicate glasses and that the ratios of densification to the total indentation volume for all the glasses correlated well with Poisson’s ratios of the glasses.
