Dense SiC-Ceramics with Specifically Adjusted Electrical Resistance (or Electrical Conductivity)

Dense, solid-state sintered SiC-ceramics and structural components produced therefrom are established over a wide range of industrial applications due to their outstanding combination of technically interesting properties (high strength and oxidation resistance up to very high temperatures, high hardness and wear resistance, comprehensive corrosion resistance, low thermal expansion, very good thermal conductivity, and favorable tribological properties). Concerning electrical properties, they usually show semiconductor behavior, which is not suitable for certain applications. By means of the described developments, such limitations were eliminated, providing special SiC-grades with adjustable high or low electrical resistance.
