These two developments ... of this calibration quickly established the ruby scale as a secondary pressure standard, and it became the de facto standard for measuring pressures in a DAC. Fig. 4. WebX-ray diffraction measurements have been carried out on cesium iodide (CsI) to 302 gigapascals with a platinum pressure standard. The results indicate that above 200 gigapascals CsI at 300 K has a hexagonal close-packed crystal structure with the ideal c/a ratio of 1.63 ± 0.01. The crystal structure and pressure-volume relations converge at high …
