Description:
Electrical conductivity
For the resistance-temperature characteristics of silicon carbide,
in a wide range of temperatures, it is exactly the opposite of the
resistance-temperature characteristics of metals. As the
temperature continues to rise, the resistivity of high-purity
silicon carbide decreases. However, the resistivity of impure
silicon carbide has a very complex relationship with temperature.
The volt-ampere characteristic curve of silicon carbide containing
aluminum impurities is nonlinear. The conductivity of silicon
carbide increases rapidly with the increase of electric field
strength, and it can be used as a semiconductor material.
Hardness, grinding ability and toughness
The crystal structure characteristics of silicon carbide itself
determine that silicon carbide has the characteristics of high
hardness, wear resistance and strong toughness. The hardness of
silicon carbide is extremely strong, only lower than several
superhard materials. The hardness of silicon carbide has a wide
range, which is the hardness of silicon carbide crystal and its
crystal axis direction. The hardness of silicon carbide varies
greatly in different crystal plane directions, and the hardness
gradually decreases with increasing temperature. The shape of
silicon carbide itself and other factors have an impact on the
toughness of silicon carbide.
