Thermal Properties of Silicon Nitride: Thermal …
20/9/2018· Silicon nitride usually offers comparatively low thermal conductivity compared to silicon carbide or aluminium nitride owing to its unique chemical composition and crystal structure. These fine ceramic grains typically grow faster in a lengthwise plane, resulting in an interlocking needle-like structure that exhibits anisotropic thermal properties.
Ceramic balls: alumina oxide, zirconia, ruby sapphire, …
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.
