Silicon Carbide (SiC) is well-known for its exceptional thermal properties, particularly its high thermal conductivity. This makes it a preferred material for various high-temperature applications.
Does SiC Have High Thermal Conductivity? 4 Key Points to Know
1. Thermal Conductivity of SiC
SiC has a thermal conductivity that ranges from 120 to 270 W/mK. This range is considered high compared to other materials, especially in the semiconductor and ceramic industries. For instance, the thermal conductivity of SiC is higher than that of common steels and cast iron, which typically do not exceed 150 W/mK. The high thermal conductivity of SiC is attributed to its strong covalent bonds and the efficient lattice structure that allows for the efficient transfer of heat.
2. Impact of Temperature on Thermal Conductivity
It is important to note that the thermal conductivity of SiC does decrease with increasing temperature. However, even at elevated temperatures, SiC maintains a relatively high level of thermal conductivity, which is crucial for its applications in high-temperature environments such as in semiconductor furnaces and metallurgical processes.
3. Other Thermal Properties of SiC
Besides high thermal conductivity, SiC also features low thermal expansion (4.0x10-6/°C), which contributes to its stability under thermal stress. This low thermal expansion, combined with its high thermal conductivity, enhances SiC's thermal shock resistance. Thermal shock resistance is the ability of a material to withstand rapid temperature changes without sustaining damage, a critical property for materials used in high-temperature applications.
4. Applications Benefiting from High Thermal Conductivity
The high thermal conductivity of SiC makes it suitable for various applications where heat management is critical. For example, SiC is used in turbine components, furnace linings, and semiconductor manufacturing equipment. In these applications, SiC's ability to conduct heat efficiently helps in maintaining stable operating temperatures and prolonging the lifespan of the equipment.
