Silicon carbide (SiC) is a crystalline material formed by the stable combination of carbon and silicon elements. Its unique structural characteristics give it many excellent physical and chemical properties, such as high temperature stability, high hardness, and corrosion resistance. These properties make silicon carbide highly valuable in many fields, especially in energy, electronics, semiconductors, ceramics, and coatings.
Compared with other materials such as silicon nitride (SiN) and silicon dioxide (SiO2), silicon carbide has higher thermal stability and chemical stability. It can still maintain excellent mechanical properties at high temperatures, and has a lower thermal expansion coefficient, making it have better performance in high-temperature applications.
Products Description
Vacuum sintered silicon carbide radiation tubes and high-temperature kilns with silicon carbide dissimilar parts have been widely used in the industrial kiln field due to their excellent high-temperature resistance and mechanical properties. The main core products and characteristics include:
I. Radiation Tube Products
As a heat-conducting and flame-isolating component for heat treatment kilns, the vacuum reaction sintered silicon carbide radiation tubes can withstand temperatures above 1600℃. By optimizing the thermal radiation efficiency, the energy efficiency of the kiln can be improved. Their surface Mohs hardness reaches level 9, and they have strong resistance to thermal shock, making them suitable for scenarios such as steel heat treatment and non-ferrous metal smelting.
Typical design: With a flame guiding sleeve structure, it guides the flame to be evenly distributed, avoiding local overheating.
Replacing traditional materials in metallurgical kilns can reduce fuel consumption by 20%, shorten production cycles, and increase kiln loading capacity. During use, the oxygen content of the combustion exhaust gas must be controlled to be less than 2% to prevent nitriding corrosion.
2. Customized Products for Special-shaped Components
High-performance components
Incorporate complex structural parts such as flame nozzles and cyclone liners, which are custom-molded using vacuum reaction sintering technology. They possess both high wear resistance and acid-base corrosion resistance. For instance, the silicon carbide liner for mining cyclones has a hardness over six times that of polyurethane, significantly extending the equipment's lifespan.
Widely applied in: high-temperature flame jet systems (such as kiln burners), wear-resistant conveying pipelines (resisting the erosion of coarse particle materials), special equipment seals and corrosion-resistant components.
3. Applications of Silicon Carbide Materials
◆ Power sector: Silicon carbide is widely used in the power industry due to its high hardness, excellent heat resistance, strong corrosion resistance, and low susceptibility to contamination, allowing it to maintain its performance for a long time.
◆ Metallurgical sector: Silicon carbide can withstand significant forces under high temperatures and pressures, and is therefore widely used in the metallurgical field, such as in alloy materials.
◆ Chemical industry: Silicon carbide has strong corrosion resistance and can withstand strong acidic and alkaline environments, making it suitable for manufacturing chemical equipment.
◆ Vehicle sector: Components made of silicon carbide do not fail or wear out under high temperatures, so they are widely used in aviation and automotive fields.
◆ Other fields: Silicon carbide can also be used in manufacturing mechanical components, bearings, refractory products, and electronic components, among others.
