摘要

摘要: 介绍了一种6-8型二级加压装置1 000 t Walker型大腔体高温高压装置中样品的组装方式、组装件材料和压力标定方法。采用碳化钨作为压砧时，获得的最高压力超过20 GPa。压力标定方法采用相变点法，即利用Bi、Tl、ZnTe、Pb、SnS、GaAs等标准压力标定物质，通过测量其在室温高压下的电阻变化，确定相变点，进而获得高压腔体内的压力与外加载荷的关系。对具有不同二级压砧截角边长（4、6、8、12 mm）组装的内部实际压力进行标定，得到了外加载荷与内部压力的关系曲线，为今后在该装置上的实验样品组装及样品实际压力确定提供了准确的数据。

Abstract: The two-stage 1 000 tons Walker module large-volume high temperature and high pressure apparatus can generate different pressures with different truncated edge lengths of anvils (12, 8, 6, and 4 mm). If tungsten carbide is chosen as an anvil, the maximum pressure obtained is above 20 GPa. The sample assemblies of Walker module apparatus are determined. The pressure calibration is performed by the fixed points of phase transitions method for different truncated edge lengths. The phase transition pressures of standard materials of pressure calibration (Bi, Tl, ZnTe, Pb, ZnS, GaAs) are achieved by measuring the resistance change with oil load under high pressure. The calibration curve of the sample pressure versus load is obtained, which provides exact information for future high pressure experiments using this apparatus.
