二级6-8型静高压装置厘米级腔体的设计原理与实验研究
Design Principles and Experimental Study of Centimeter-Scale Sample Chamber for Two-Stage 6-8 Type Static High Pressure Apparatus
摘要
Abstract
By analyzing experimental data,we put forward the concept of the limit compression volume ratio and the general design principles of centimeter magnitude sample chamber for two-stage 6-8 type static high pressure apparatus.Based on the limit compression volume ratio,we designed an assembly of 36/20 (Octahedral edge-length 36 mm/anvil truncation edge-length 20 mm)with high pressure generating efficiency.Pressure calibration at room temperature for the 36/20 assembly was performed using the phase transitions of Bi (Ⅲ-Ⅴ,7.7 GPa),ZnTe (Ⅰ-Ⅱ,5 GPa;Ⅱ-Ⅲ,8.9-9.5 GPa;semicon-ductor-metal,1 1.5-13.0 GPa)and ZnS (semiconductor-metal,15.6 GPa).The experimental results show that the pressure of sample chamber exceeds 15 GPa and the sample diameter reaches 1 cm.The improvements of two-stage 6-8 type static high pressure apparatus have great potential applications in high-pressure experimental research and industrial production.关键词
