HIGH PRESSURE AND HIGH TEMPERATURE APPARATUS

摘要

A design for high pressure/high temperature apparatus and reaction cell to achieve SIMILAR 30 GPa pressure in SIMILAR 1 cm volume and SIMILAR 100 GPa pressure in SIMILAR 1 mm volumes and 20-5000 DEG C temperatures in a static regime. The device includes profiled anvils (28) action on a reaction cell (14, 16) containing the material (26) to be processed. The reaction cell includes a heater (18) surrounded by insulating layers and screens. Surrounding the anvils are cylindrical inserts and supporting rings (30-48) whose hardness increases towards the reaction cell. These volumes may be increased considerably if applications require it, making use of presses that have larger loading force capability, larger frames and using larger anvils.
