Abstract: A capsule assembly for an ultra-high pressure furnace, comprising a containment tube having an interior side surface and defining a central longitudinal axis; a chamber suitable for accommodating a reaction assembly, a proximate and a distal end heater assembly, and a side heater assembly. When assembled, the chamber is contained within the containment tube and arranged longitudinally between the proximate and distal end heater assemblies. The side heater assembly is disposed adjacent the interior side surface and electrically connects the end heater assemblies with each other. Each end heater assembly has a respective peripheral side disposed adjacent the interior side surface Heat is produced in the chamber in response to an electric current flowing through the end and side heater assemblies. At least a proximate side heater barrier spaces apart the side heater assembly from at least the proximate end heater assembly, adjacent its peripheral side, operative to prevent a portion of the side heater assembly from intruding between the peripheral side of the proximate end heater assembly and the containment tube and short-circuiting at least part of the proximate end heater assembly, when the end heater assemblies move towards each other in response to a force applied by the ultra-high pressure furnace onto the capsule assembly along the central longitudinal axis.

Abstract: A capsule assembly for an ultra-high pressure furnace, comprising a containment tube defining a central longitudinal axis, a chamber suitable for accommodating a reaction assembly, a proximate and a distal end heater assembly, and a side heater assembly. When assembled, the chamber and the side heater assembly are contained within the containment tube and arranged longitudinally between the proximate and distal end heater assemblies. Each end heater assembly comprises a respective conduction volume forming a respective electrical path through the end heat assembly. The side heater assembly electrically connects the respective conducting volumes to each other, and heat is produced in the chamber in response to an electric current flowing through the side heater assembly and the conducting volumes. At least the proximate end heater assembly comprises a first insulation component including an outer insulation volume. The conducting volume of at least the proximate end heater assembly includes an inner conducting volume, and the inner conducting volume is laterally spaced apart from the containment tube by the outer insulation volume.

Abstract: Large-scale manufacturing of gallium nitride boules using m-plane or wedge-shaped seed crystals can be accomplished using ammonothermal growth methods. Large-area single crystal seed plates are suspended in a rack, placed in a large diameter autoclave or internally-heated high pressure apparatus along with ammonia and a mineralizer, and crystals are grown ammonothermally. The orientation of the m-plane or wedge-shaped seed crystals are chosen to provide efficient utilization of the seed plates and of the volume inside the autoclave or high pressure apparatus.
