Abstract
An apparatus for processing materials at high temperatures comprises a high strength enclosure; a plurality of high strength radial segments disposed adjacent to and radially inward from the high strength enclosure; a liner disposed adjacent to and radially inward from the radical segments; a chamber defined interior to the liner; a heating device disposed within the chamber; and a capsule disposed within the chamber, the capsule configured to hold a supercritical fluid. The apparatus may be used for growing crystals, e.g., GaN, under high temperature and pressure conditions.
