Abstract
A porous form body is produced of sinterable SiC-powder by forming a suitable suspension of said SiC-powder and then treating the suspension to convert it into droplets and the droplets into a granular material in which the granules are substantially larger than the particles of SiC-powder. The granular material is then formed into a green body, e.g. by spraying the granules onto a negative mold of the form body or slip-casting or the like. The green body is then sintered whereby the resulting porosity in the final form body provides the form body with low drag.
