Silicon carbide possesses many important features. It is very hard, mechanically and chemically resistanced, and retains these properties to high temperature. Because of this, it is an excellent material for ceramic composite matrix. The second, dispersed phase should modify selected properties of SiC. The authors investigations were focused on the preparation of the SiC-based composites for structure application, therefore mechanical properties of the materials were mainly controlled. Simultaneously, electrical properties were also measured for to apply such materials as high-temperature ceramic resistors. The following systems were investigated: SiC-C, SiC-B4C, SiC-TiC and SiC-TiB2. The experiments showed that mechanical and electrical properties could be controlled, particularly a doubled fracture hardness and considerable increasing of strength were noticed. The electrical resistance could be changed by 10 raising to a power 8th times.
