Abstract

For the production of mouldings of silicon-infiltrated silicon carbide, in particular of pipes, a mixture of silicon carbide powder, organic binder and optionally carbon is moulded to give a cylindrical elongated green compact, the binder of the green compact is removed in a nonoxidising atmosphere by carbonisation at about 1000 DEG C and the porous blank obtained is siliconised by the action of liquid silicon at temperatures of at least 1400 DEG C. During the siliconisation, the blank rests on a porous SiSiC support which is in contact with liquid silicon. The SiSiC support has a straight channel with an angular cross-section and recesses in which the cylindrical blank to be siliconised is placed, and the SiSiC support has downward-projecting side walls whose lower surface is in contact with the liquid silicon. <IMAGE>
