Abstract
A design for high pressure/high temperature apparatus and reaction cell to achieve ˜30 GPa pressure in ˜1 cm volume and ˜100 GPa pressure in ˜1 mm volumes and 20-5000° 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.
Claims18
High pressure/high temperature apparatus for material processing comprising:
- a) a pair of confronting profiled anvils, said confronting profiled anvils forming a cavity therebetween;
- b) a reaction cell for holding the material to be processed, said reaction cell being disposed in the cavity formed between the profiled anvils;
- c) cylindrical inserts disposed above and below said anvils;
- and
- d) at least one annular supporting ring surrounding said profiled anvils.
A reaction cell for processing materials under high temperature and pressure comprising:
- a) a cylindrical graphite ceramic container for holding the material to be processed, said container becoming heated when an electrical current is passed therethrough;
- b) a first graphite screen spaced apart from and surrounding said container;
- c) first insulating material disposed between said container and said first screen;
- d) a second graphite screen spaced apart from and surrounding said first graphite screen;
- e) second insulating material disposed between said first screen and said second screen.
