Silicon carbide (SiC) is a material that can withstand extremely high temperatures.
It can maintain its mechanical strength up to 1,400˚C.
SiC can operate at even higher temperatures, well in excess of 2,400°F (1,316°C), especially in radiant tube applications.
1. High Temperature Resistance
Silicon carbide is famous for its ability to maintain high mechanical strength at temperatures as high as 1,400˚C.
This makes it perfect for applications where high temperatures are common.
Beyond 1,400˚C, SiC can still be used effectively in environments where temperatures exceed 2,000°F (1,093°C).
For example, in radiant tubes, SiC elements must be properly supported to avoid distortion and should be centered using a refractory spacer.
2. Use in Radiant Tubes
In situations where metallic elements like chromium and nickel are not suitable due to their limited temperature tolerance, SiC becomes a great alternative.
When used as a bayonet element inside a radiant tube, SiC can operate at temperatures well above 2,000°F (1,093°C).
This is important in industrial processes that need extreme heat, where SiC not only meets the thermal demands but also offers better resistance to chemical corrosion compared to other ceramics.
3. Thermal Conductivity and Oxidation
SiC has a high thermal conductivity, ranging from 120-270 W/mK, which is higher than that of common steels and cast iron.
This high thermal conductivity helps in efficiently distributing heat, which is beneficial in high-temperature applications.
However, it's important to note that thermal conductivity decreases with increasing temperature, and this must be considered in specific applications.
In terms of oxidation, SiC can be thermally oxidized into SiO2, which requires temperatures between 1,200 - 1,600 °C.
This oxidation process is crucial for certain applications and shows another aspect of SiC's high-temperature capabilities.
4. Conclusion
Silicon carbide's ability to withstand extreme temperatures, along with its high thermal conductivity and resistance to chemical corrosion, makes it a valuable material in high-temperature industrial applications.
Its use in radiant tubes and as a bayonet element further highlights its suitability for environments where other materials fail due to thermal limitations.
