Silicon carbide is an artificial mineral with a strong covalent bonding. It is superior to alumina and silicon nitride in hardness. And it is good in abrasion-resistance, especially in a stick-slip condition. It maintains mechanical strength at a high temperature. Besides, it
Ceramic matrix composite - Wikipedia
The silicon carbide matrix is a good thermal conductor. Electrically, it is a semiconductor , and its resistance therefore decreases with increasing temperature. Compared to (poly)crystalline SiC, the amorphous SiC fibers are relatively poor conductors of heat and electricity.
Quick Answer: Is Cement A Ceramic Material? - Ceramics
A ceramic material is an inorganic, non-metallic, often crystalline oxide, nitride or carbide material. Some elements, such as carbon or silicon, may be considered ceramics. Ceramic materials are brittle, hard, strong in compression, and weak in shearing and tension.

Material properties of diamond - Wikipedia
Unlike most electrical insulators, diamond is a good conductor of heat because of the strong covalent bonding and low phonon stering. Thermal conductivity of natural diamond was measured to be about 2200W/(m·K), which is five times more than silver , the most thermally conductive metal.

Graphite @ Chemistry Dictionary & Glossary
Graphite is a good conductor of heat and electricity. The layers cleave easily, making graphite useful as a solid lubricant. A process to make pure synthetic graphite was invented by the American chemist Edward Goodrich Acheson (1856–1931).
Suppliers of Silicon Alloys
Silicon is a metalloid; it has characteristics of both metals (shiny metallic appearance, strong) and non-metals (brittle, not a good conductor of electricity). After being isolated as an element it was originally called Silicium, the "ium" suffix denoting a metal in the same fashion as Aluminium.

Graphite – Structure, Properties and Types
Graphite is a good conductor of electricity due to its free delocalized electron which is free to move throughout the sheets. Graphite is insoluble in organic solvents and water, this is because the attraction between solvent molecules and carbon atoms is not strong enough to overcome the covalent bonds between the carbon atoms in the graphite.

The difference in the conductivity means that a much larger size aluminium conductor needs to be used to match the conductivity of the equivalent copper conductor. Using a larger size conductor has the add-on effect of requiring a greater amount of insulation material to adequately cover the conductor and the extra cross-sectional size of the cable may be restrictive in certain appliions.
