An anvil-preformed gasket system has been developed to extend the pressure range for the widely used large volume cubic press without sacrificing the sample volume. The relationship of the sample chamber pressure versus press load for this system was calibrated at room temperature using transitions in Bi, Tl, and Ba. With similar sample volumes (8-11 mm in diameter and 8 mm in length), the anvil-preformed gasket system can generate pressures up to about 8.5 GPa, significantly higher than 6 GPa, which was generally the maximum pressure for the conventional anvil-gasket system. The details on the optimized design for the anvil-preformed gasket system are given in this note.
已开发出一种预成型砧座垫片系统,以扩展广泛使用的大体积立方压机的压力范围,同时不牺牲样品体积。该系统的样品腔压力与压机负载之间的关系在室温下通过铋、铊和钡的相变进行了校准。在类似的样品体积(直径8 - 11毫米,长度8毫米)下,预成型砧座垫片系统可产生高达约8.5吉帕的压力,显著高于传统砧座垫片系统通常的最大压力6吉帕。本说明给出了预成型砧座垫片系统优化设计的详细信息。
