They indicate that the application of Fe 0.79Si 0.07B 0.14 metallic glass gaskets in XRD experiments for both axial and radial geometries substantially improves various aspects of megabar experiments and, in particular, the signal-to-noise ratio in comparison to that with conventional gaskets made of Re, W, steel or other crystalline metals.
Our results emphasize the material’s importance for a great number of delicate experiments conducted under extreme conditions.
Ne, H 2) used as pressure-transmitting media or in those with laser heating in a DAC. We report that Fe 0.79Si 0.07B 0.14 metallic glass gaskets offer a stable sample environment under compression exceeding 1 Mbar in all XRD experiments described here, even in those involving small-molecule gases ( e.g. The experiments were conducted in either axial or radial geometry with X-ray beams of micrometre to sub-micrometre size. In this work, we studied the performance of gaskets made of metallic glass Fe 0.79Si 0.07B 0.14 in a number of high-pressure X-ray diffraction (XRD) experiments in DACs equipped with conventional and toroidal-shape diamond anvils.
