PRESSURE REACTOR FOR PRODUCING MATERIALS HAVING DIRECTED POROSITY

A pressure reactor for producing materials having directed porosity, the pressure reactor comprising: a pressure chamber provided with a gas inlet valve and covers detachably connected thereto, the pressure chamber connected to a vacuum installation and having an external cooling jacket; wherein inside of the pressure chamber; a retractable, removable, demountable crystallizer located inside of said pressure chamber attached to one of said covers; a retractable melting furnace with an internal removable crucible attached to a second cover; a heater in a form of a heating element encapsulated with an insulation in a form of ceramic beads provided between an inner housing of the melting furnace and the crucible, wherein a drain hole of the crucible is directed in the direction of an inlet filling hole of the crystallizer; an intermediate element fastened between the melting furnace and the crystallizer; wherein the pressure chamber is rotatably mounted in a supporting frame in a manner allowing its rotation around a transverse axis passing through its centre of symmetry.
