Section: claims

1. A container for the consolidation of material under elevated pressure and temperature conditions, comprising:an outer cylinder; andan inner cylinder comprising internal compression plates that are positioned between the inner and outer cylinders and curved to match the radius of the inner and outer cylinders, wherein said compression plates are arranged in rows and with predetermined spacing, axially, radially, or both. 2. The container of claim 1, wherein the material comprises hazardous, toxic, or radioactive waste, and the container is configured to hold such waste without releasing it to the environment. 3. The container of claim 1, wherein the inner and outer cylinders are made from metal comprising steel, nickel, titanium, aluminum, copper, alloys thereof, or combinations thereof, wherein the inner cylinder has at least one different characteristic from the outer cylinder, said characteristic comprising malleability, corrosion resistance, or wall thickness. 4. The container of claim 1, wherein the inner cylinder comprises a layer that is chemically reactive with the material located in the container. 5. The container of claim 4, wherein said layer comprises titanium in an amount sufficient to (i) react with oxygen that degases from the waste material being consolidated, (ii) control the redox of the powdered waste material, or (iii) combinations thereof. 6. The container of claim 1, wherein the outer cylinder has a wall thickness that is thicker than the inner cylinder. 7. The container of claim 1, wherein the internal compression plates comprise a material that has a higher strength than the inner cylinder, the outer cylinder, or both, such that it resists collapse and deformation under hot isostatic pressing conditions, wherein said material comprises a metal, ceramic, graphite or combinations thereof. 8. The container of claim 7, wherein the internal compression plates are configured to touch at least one other compression plate during hot isostatic pressing. 9. The container of claim 8, wherein the internal compression plates comprise right angled edges. 10. The container of claim 7, wherein the internal compression plates have angled or recessed edges to cause interlocking or guide the plates to slide over each other during hot isostatic pressing. 11. The container of claim 1, further comprising a liner configured around the compression plates that help lock the plates into position. 12. The container of claim 1, wherein the outer cylinder comprises walls of sufficient thickness to allow the walls to remain straight after being exposed to said elevated pressure and temperature conditions. 13. A method of producing a consolidated article, the method comprising:filling a container with material to be consolidated, the container comprising:an outer cylinder;an inner cylinder comprising internal compression plates that are positioned between the inner and outer cylinders and curved to match the radius of the inner and outer cylinders, wherein said compression plates are; andcollapsing the by applying heat and/or pressure to the container such that the internal compression plates cause the container to collapse in a predictable manner while consolidating the material in the container to produce a consolidated article having a predictable shape and/or dimension. 14. The method of claim 13, further comprising evacuating and sealing the container prior to consolidating. 15. The method of claim 13, wherein the material comprises hazardous, toxic, or radioactive waste, and the container is configured to hold such waste without releasing it to the environment. 16. The method of claim 13, further comprising configuring the plates to resist collapse during consolidation are lined up in rows and with predetermined spacing both axially and radially. 17. The method of claim 13, further comprising reacting the material to be consolidated with at least one material located on or within the inner cylinder. 18. The method of claim 17, wherein the material located on or within the inner cylinder comprises titanium, and said reacting comprises (i) reacting with oxygen that degases from the waste material being consolidated, (ii) controlling the redox of the powdered waste material, or (iii) combinations thereof. 19. The method of claim 13, wherein collapsing the by applying heat and/or pressure to the container comprises hot isostatic pressing at a temperature ranging from 800 to 1400° C. and pressure ranging from 10-300 MPa for a time ranging from 8 to 14 hours.
