Abstract
A high pressure apparatus and related methods for processing supercritical fluids is described. The apparatus includes a capsule, a heater, at least one ceramic ring with one or more scribe marks and/or cracks present. The apparatus optionally has a metal sleeve containing each ceramic ring. The apparatus also has a high-strength enclosure, end flanges with associated insulation, and a power control system. The apparatus is capable of accessing pressures and temperatures of 0.2-2 GPa and 400-1200° C., respectively.
Claims24
Apparatus for high pressure material processing comprising:
- a cylindrical capsule region having a length;
- a structure configured to provide axial confinement of pressure generated within the cylindrical capsule region;
- an annular heating member enclosing the cylindrical capsule region;
- and
- at least two assembled rings disposed around a perimeter of the annular heating member and configured to provide radial confinement for pressure generated within the cylindrical capsule region, each of the at least two assembled rings comprising a high strength enclosure ring surrounding an annular ceramic member having a thickness, the annular ceramic member being made of a material having a compressive strength of at least 0.5 GPa and a thermal conductivity of less than about 4 watts per meter-Kelvin;
- wherein an interface between two adjacent assembled rings is located at a position along the length of the cylindrical capsule region.
Apparatus for high pressure material processing comprising:
- a cylindrical capsule region comprising a first region and a second region, and a length defined by a length the first region and a length of the second region;
- an annular heating member enclosing the cylindrical capsule region;
- a structure configured to provide axial confinement of pressure generated within the cylindrical capsule region;
- and
- at least two continuous annular cermet members having a thickness disposed continuously around a perimeter of the annular heating member and configured to provide radial confinement for pressure generated within the cylindrical capsule region, each of the at least two continuous annular cermet members being made of a material having a compressive strength of at least 0.5 GPa and a thermal conductivity of less than 100 watts per meter-Kelvin;
- and
- a high strength enclosure ring disposed surrounding each of the at least two continuous annular metal or cermet members to form a high strength enclosure stack,
- wherein an interface between two adjacent continuous annular cermet members is located at a position along the length defined between the first region and the second region.
Apparatus for growing crystals comprising:
- a cylindrical capsule having a length;
- a supercritical fluid disposed within the cylindrical capsule;
- an annular heater surrounding at least a portion of the cylindrical capsule;
- at least two ceramic rings surrounding the annular heater, a metal enclosure ring surrounding each of the at least two ceramic rings, and
- a structure configured to provide axial confinement of pressure generated within the cylindrical capsule;
- wherein the at least two ceramic rings and the metal enclosure are configured to provide radial confinement for pressure generated within the cylindrical capsule;
- and
- wherein an interface between two adjacent ceramic rings is located at a position along the length of the cylindrical capsule.
