Abstract

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.

摘要

为了在高压实验中使样品腔的厚度最大化，我们进行了测试并开发了与用于金刚石对顶砧的立方氮化硼（c-BN）垫片相关的技术。c-BN垫片提供的样品腔比传统金属垫片厚几倍。我们已经开发出制备垫片和向腔室中填充样品的方法。通过使用c-BN垫片，我们成功测量了高达100吉帕斯卡的低Z值非晶态样品SiO2玻璃的X射线衍射图谱。
