Silicon carbide is highly hard up to 2800 HV with good wear resistance. It has very high temperature stability with maximum service temperatures of up to 1650°C, besides high thermal conductivity of 100-120 W/m·K at higher temperature conditions. It also has high thermal shock resistance due to its low thermal expansion coefficient. Silicon carbide contains hard, flexural-strength, and dense corrosion-resistant forms with near-zero open porosity, extremely resistant to harsh mechanical and chemical environments.
Reaction-Bonded Silicon Carbide (RBSiC) and Sintered Silicon Carbide (SSiC) are the two most typical types of silicon carbide. They have different properties for a variety of applications.
① Manufacturing Process: RBSiC is made through infiltrating a carbon-containing preform with molten silicon at a lower temperature (around 1600℃). SSiC is a fully dense material achieved by pressureless sintering high-purity SiC powder with sintering aids at a much higher temperature (1950-2200℃).
② High-Temperature Performance: The strength of RBSiC reduces above 1350°C. SSiC maintains over 90% of its strength at 1600°C.
③ Mechanical Properties: SSiC generally has higher density and strength. It has higher thermal conductivity and can sustain higher mechanical loading at high temperatures. RBSiC is of lower thermal conductivity and is more susceptible to loss in strength at high-temperature environments.
④ Corrosion Resistance: SSiC is more corrosion-resistant to all acids and bases, including hydrofluoric acid and molten salts.RBSiC is vulnerable to attack by hydrofluoric acid and strong bases.
Silicon carbide is used in the production of high-voltage power devices for inverters of electric vehicles, industrial power supply and solar converters, at a minimum of 50% decrease in energy loss. SiC components in 5G base stations support high-power and high-frequency applications. Components such as wafer chucks and etch rings have high plasma corrosion resistance, enhancing wafer yield. SiC composite components in jet engines can withstand up to 1500℃ and reduce weight by 30%. It is also being used in rocket nozzles and hypersonic vehicle nose cones as it is capable of high-speed thermal variations and extreme aerodynamic heating.
Silicon carbide is more costly initially than a traditional material such as alumina because of its costly and energy-intensive process. However, less maintenance, greater efficiency and extended life of parts do recover costs on silicon carbide parts.
Silicon carbide’s hardness and durability provide wear-resistant bushings and kiln furniture to endure much longer than more traditional materials. It reduces the number of replacements, abolishing production shutdowns and labor charges associated with maintenance. SiC can have a service lifetime of 3-6 years; a low replacement rate means significant cost savings.
Silicon carbide has greater thermal conductivity and can handle higher temperatures. In heating devices and heat exchangers, it can increase the efficiency of energy transfer, resulting in less energy consumption in the long term. In power electronics, SiC products reduce power loss, leading to a reduced system cost.
