Ultrafine silicon carbide powders of two types were used as fillers for synthesis of porous ceramics. The first powder was obtained by the furnace method (SiCF), the second sample was synthesized using the SHS technology (SiCSHS). The fillers had identical average particle size, but different morphology of their surface. It is established that with the same size, the morphology of initial powder components determined structural parameters and characteristics of the synthesized porous ceramics. It determines effective applicability of various materials for ultrafiltration or catalysis processes.
