| Abstract | A massive cubic press, with a maximum load of 1400 tons on every WC anvil, has been installed at the High Pressure Laboratory of Peking University. High-P experiments have been conducted to examine the performance of the conventional experimental setup and some newly developed assemblies adopting the anvil-preformed gasket system. The experimental results suggest that (1) the conventional experimental setup (assembly BJC2-0) can reach pressures up to about 6 GPa with a large cell volume of 34.33 cm(3); (2) the anvil-preformed gasket system, despite decreasing the P-generating efficiency, extends the P-generating capability up to about 8 GPa at the expense of reducing the cell volume down to 8.62 cm(3) (assembly BJC2-6); (3) due to the large cell volume, it is possible to make further modifications to extend the pressure range, as readily demonstrated, to about 10 GPa (assembly BJC5-7); (4) the effect of high temperature on the pressure generation of the press is not significant. It follows that this cubic press can be very useful in synthesizing materials of large volume at high pressures and to the studies such as high-P phase equilibrium, trace element partitioning and isotope fractionation in the research fields of Earth and planetary sciences. |
