Three-dimensional (3D) visualization of a material under pressure can provide a great deal of information about its physical and chemical properties. We developed a technique combining in-house x-ray computed tomography (XCT) and a diamond anvil cell to observe the 3D geometry of a sample in situ at high pressure with a spatial resolution of about 610 nm. We realized observations of the 3D morphology and its evolution in minerals up to a pressure of 55.6 GPa, which is comparable to the pressure conditions reported in a previous synchrotron XCT study. The new technique developed here can be applied to a variety of materials under high pressures and has the potential to provide new insights for high-pressure science and technology.

基于实验室的 X 射线计算机断层扫描，用于在高压下对金刚石砧座中的样品进行 3D 成像

压力下材料的三维 (3D) 可视化可以提供有关其物理和化学特性的大量信息。我们开发了一种结合内部 X 射线计算机断层扫描 (XCT) 和金刚石砧座的技术，以在高压下原位观察样品的 3D 几何形状，空间分辨率约为 610 nm。我们实现了对 55.6 GPa 压力下矿物的 3D 形态及其演化的观察，这与之前同步加速器 XCT 研究中报告的压力条件相当。这里开发的新技术可以应用于高压下的各种材料，有可能为高压科学和技术提供新的见解。
