为了在高压实验中最大限度地增加样品室的厚度，我们进行了测试，并开发了与金刚石砧座用立方氮化硼（c-BN）垫圈相关的技术。c-BN垫圈提供比传统金属垫圈厚几倍的样品室。我们已经开发了准备垫圈和用样品填充腔室的方法。通过使用c-BN垫片，我们已经成功地测量了SiO2玻璃，低Z非晶样品的X射线衍射图案，高达100 GPa。
To maximize the thickness of the sample chamber in high-pressure experiments, we have conducted tests and have developed techniques relevant to the cubic boron nitride (c-BN) gasket for diamond-anvil cells. The c-BN gasket provides a sample chamber several times thicker than conventional metal gaskets. We have developed methods to prepare the gasket and to fill the chamber with the sample. By using the c-BN gasket, we have successfully measured x-ray diffraction patterns of SiO2 glass, a low-Z noncrystalline sample, up to 100 GPa.
