US 2022/0152966 A1 · MULTI-ANVIL HIGH PRESSURE PRESS AND RELATED METHODS

Abstract

A high-temperature, high-pressure (HTHP) press is provided having a plurality of press bases. In one embodiment, the press includes eight or more press bases arranged in one of an octahedral, a dodecahedral or an icosahedral geometry. The press bases may include, or be coupled with, anvils configured to converge on a central region. An octahedral, a dodecahedral or an icosahedral reaction cell may be positioned at the central region for pressing by the converging anvils. In one embodiment, the reaction cell may include an opening, such as a through-hole, extending from a first face of the reaction cell to a second, opposite face of the reaction cell. One or more canisters containing materials to be sintered may be disposed in the opening to be subjected to a HTHP process.

Dependent claims

A high-temperature, high-pressure (HTHP) press comprising:

a plurality of press bases arranged in an icosahedral geometry;
wherein:
each press base includes a body portion housing a piston, the piston being displaceable toward a central region of the press;
each press base includes an anvil coupled with the piston;
each anvil includes an engagement surface and a side surface, wherein each anvil is displaceable along an associated centerline relative to a center region associated with an intersection of the centerlines;
and
when each of two adjacent anvils of the plurality of anvils is displaced along the associated centerline thereof at a rate of {dot over (x)}, the side surfaces of each of the two adjacent anvils are displaced towards each other at a rate of ġ, and wherein the ratio of ġ/{dot over (x)} is 0.357.
