The invention relates to a structure element (1, 6, 10, 14, 31) of a device for the treatment of corrosive materials in heat and stress conditions. The structure element is comprised of monomers which are mass polymerized in a closed mold, said element being comprised of a single piece so as to seal the corrosive material when the element is placed in the device and when an external stress is exerted on said device. |
