Silicon carbide maintains its strength even at temperatures up to 1400 C. Notable features of this material are extremely high thermal conductivity and electrical semiconductivity. Silicon nitride has high hardness and corrosion reisistance due to its chemical and physical stability.
Silicon nitride bearing balls have a coefficient of thermal expansion just 25% if most steel balls, so there is less friction generated in the bearing as heat increases. The low thermal conductivity of silicon nitride balls reduces the amount of heat absorbed, thus reducing cooling system requirements.

Silicon Carbide (SiC) and Gallium Nitride (GaN) The key for the next essential step towards an energy-efficient world lies in the use of new materials, such as wide bandgap semiconductors which allow for greater power efficiency, smaller size, lighter weight, lower overall cost – or all of these together.
Renishaw: Styli materials
Silicon nitride does not have an attraction to aluminium and so does not exhibit the adhesive wear seen with ruby in similar appliions. However, silicon nitride does show significant abrasive wear characteristics when scanning on steel surfaces and so its appliions are best confined to aluminium.
Non-oxide Ceramics – Silicon Carbide (SiSiC/SSiC)
Worth knowing: Properties of Silicon Carbide (SSiC / SiSiC) Low density (3.07 to 3.15 g/cm 3) High hardness (HV10 ≥ 22 GPa) High Young’s modulus (380 to 430 MPa) High thermal conductivity (120 to 200 W/mK) Low coefficient of linear expansion (3.6 to 4.1x10-6 /K at 20 to 400 C)
Silicon Carbide is produced by heating silica sand and a carbon source, typically petroleum coke, to high temperatures in a large, open “Acheson” furnace. The result of this high temperature process is the crystalline formation of Silicon Carbide grains, of both Green and Black coloring.
