摘要：

A new split-sphere large-volume high pressure apparatus has been developed to generate high pressure above 10 GPa. The apparatus is based on a domestic hinge-type cubic-anvil press known as the DS6 x 800T press. In this work, the split-sphere parts are directly placed in the cubic-anvil cell, and the effect of the gasket dimension and phyrophyllite density on pressure,transmitting efficiency has been investigated. The relationship of cell pressure versus press load was calibrated at room temperature for the 14/8 (octahedral edge-length/anvil truncation edge-length, in millimeters) cell assembly using the phase transitions of Bi I - II (2.55 GPa), III - V (7.7 GPa), and Sri I - II (9.4 GPa). The experimental results show that the cell pressure can reach about 10 GPa with a sample volume of 3-4 mm under an applied load of 290 ton.
