Silicon Carbide: Core Application Scenarios

2025-09-17

Silicon carbide (SiC), with its high hardness, high-temperature resistance, corrosion resistance, and semiconductor properties, has become a "super material" in many fields. Key applications include:

一，Semiconductor electronics
（1）Electric vehicle inverters: SiC MOSFETs improve efficiency by 5-10% and extend battery life by 7%; Photovoltaic inverters: SiC diodes reduce energy consumption by 30%
（2）5G base station power amplifier efficiency increases by 40%; Low-orbit satellites, 600°C+ sensors, and room-temperature quantum bits (coherence 10ms) all use SiC

二，Defense and aerospace
（1）Hyper-super-high missile fairings have a wave transmission of >90%; SpaceX rocket nozzles withstand temperatures exceeding 3000°C
（2）Telescope SiC mirror deformation is <1 nanometer; Satellite structural components reduce weight by 30%

三，Industrial energy
（1）Chemical pump bearing life is 10 times that of stainless steel; Steel mill lining wear resistance is increased by 8 times; Nuclear fuel cladding withstands 60 dpa irradiation
（2）1600°C+ furnace lining reduces fuel consumption 35%; geothermal drill bits are resistant to high and low temperature acids.

四，Optical infrared
Infrared missile lenses, deep ultraviolet LEDs (for sterilization), industrial inspection windows, and more rely on SiC.

五，Emerging environmental technologies
（1）Modified SiC catalytic propylene selectivity > 90%; Solid-state battery conductivity improved by adding SiC
（2）Lithium battery recycling linings have a lifespan five times that of enamel.

六，Traditional cutting-edge
（1）Black SiC for metal grinding, green SiC for carbide polishing; glass kiln furniture has a 10-year lifespan and a 90% cost reduction.
（2）3D-printed SiC parts; artificial joints have a 5-year survival rate of 97.3%.

七，Market

Global market size from $1.32 billion to $8.23 billion (CAGR 14.9%) from 2024 to 2037. 8-inch wafers and trench gates have seen a 40% cost reduction, with China accelerating domestic substitution.
SiC will power both technological and energy transformations.
