FIELD: metallurgy.
SUBSTANCE: invention relates to the workpieces from porous materials volumetric metallization plant high-temperature reactor. Reactor comprises housing with lining in the form of carbon powder backfilling and/or the low thermal conductivity fibrous carbon filler placement into the dense, heat-resistant material containers, vertically arranged relative to the reactor bottom, pre-sealed U-shaped shells of carbon-carbon or carbon-silicon carbide composite material, having hermetic bushings for the temperatures in the reactor measuring through them, at that, by their ends the U-shaped shells are installed through the seals and / or sealant into the made in the reactor bottom recesses with hermetic toroidal chambers formation, inside which filled with the heat-insulating material and closed with lids containers are located, wherein the sealed chambers are provided with fittings for direct connection to the vacuum system. At that, before toroidal chambers the cylindrically shaped heat shields are placed, from the previously sealed carbon-carbon or carbon-silicon carbide composite material, part of which can be made in the form of the Archimedes spiral, and the hermetic bushings are made in one piece with the U-shaped shells.
EFFECT: enabling increase in the workpieces volumetric metallization quality.
