本文基于高压研究及超硬材料生产所用的静高压立方大腔体(六面顶)压机的需要, 制备了源于南非叶腊石矿的两种(A和B)叶腊石粉压块, 并与同工艺国产(北京门头沟)黄色叶腊石粉压块进行比较, 以此建立评估叶腊石传压及密封性能的实验方法与物理判据. 采用Bi, Tl, Ba等标压物质原位标定了以上3种叶腊石压腔中心位置及密封边处的压力; 同时, 采用银熔点法分别获得了3种叶腊石作传压密封材料时高温下腔体压力与系统加载的对应关系. 结果表明, 在相同加载油压下南非叶腊石B粉压块和国内叶腊石粉压块中心位置的压力差值不超过0.1 GPa, 在升压和降压过程中叶腊石块中心位置与密封边位置的压力差值也更为相近. 相比于南非叶蜡石A粉压块, B粉压块在高温传压和密封性能上更接近国产叶腊石粉压块.

Owing to the need for a hydrostatic high-pressure cubic large cavity (hexahedral top) press used in high-pressure research and production of superhard material, two kinds of pyrophyllite powder compacts (A and B) from pyrophyllite mine in South Africa are prepared, and compared with the domestic yellow pyrophyllite powder compacts (Mentougou, Beijing) produced by the same process, to establish experimental methods and physical criteria for evaluating the pressure transmission and sealing performance of pyrophyllite. During the experiment, standard pressure materials such as Bi, Tl, and Ba are used to in-situ calibrate the pressure at the central positions and sealing edges of the pyrophyllite pressure chambers from the three aforementioned compacts under normal pressure conditions. Additionally, the silver melting point method is employed to obtain the corresponding relationship between chamber pressure at high temperature and system loading when using these three types of pyrophyllite as load-transmitting sealing materials. The results show that under the same hydraulic pressure loading, the difference in pressure at the central position between South African pyrophyllite B powder blocks and domestically produced pyrophyllite powder blocks does not exceed 0.1 GPa. Furthermore, in pressurization process and depressurization processe, the differences in pressure between the central position and the sealing edge of the pyrophyllite blocks are notably similar. Compared with South African pyrophyllite A powder blocks, pyrophyllite B powder blocks exhibit a closer resemblance to domestically produced pyrophyllite powder blocks in terms of high-temperature load transmission and sealing performance. Pyrophyllite B powder blocks from South Africa have the potential to serve as a substitute for domestically produced pyrophyllite without changing the existing superhard material synthesis process, making them promising candidates for use as load-transmitting media and sealing materials. These research findings hold significant academic importance in the realms of high-pressure research and superhard material production. They provide valuable insights into the selection of suitable transmission and sealing materials and the optimization of high-pressure experimental conditions. Additionally, this study presents robust method and criteria for experimental procedures and performance assessment.-
