Process for the isothermal and isobaric chemical gas infiltration or refractory materials into a porous structure comprises sealing a part of the surface of a porous structure

摘要

Isothermal and isobaric chemical gas infiltration or refractory materials, especially carbon, into a porous structure comprises sealing at least one part of the surface of a porous structure subjected to educt gas, and inserting the porous structure into the reactor so the diffusion path for the gas is lengthened in the structure. Preferred Features: Sealing is carried out using a graphite foil which is adhered to the relevant part of the surface of the porous structure using an organic adhesive.
