Abstract

In order to siliconise porous mouldings of silicon carbide/carbon, a mixture of silicon carbide powder, organic binder and optionally carbon is moulded to give a green compact, the binder of the green compact is removed in a nonoxidising atmosphere by carbonisation at about 1000 DEG C and the blank obtained is siliconised by the action of molten silicon, the blank obtained resting on a porous SiSiC support whose lower part is in contact with the liquid silicon, and the arrangement of SiSiC support and resulting moulding being cooled after the end of siliconisation. The support used is a dense packing of porous SiSiC rings which are arranged parallel to one another and at right angles on a graphite combustion plate which is charged with silicon and is impermeable to liquid silicon.
