Against the backdrop of continuous global industrial upgrading and breakthroughs in new material technologies, silicon carbide (SiC) has emerged as one of the most outstanding non-oxide ceramic materials, ushering in unprecedented market opportunities. With its ultra-high hardness, excellent thermal conductivity, chemical stability, and high-temperature resistance, silicon carbide has become an indispensable raw material in critical industries such as abrasives, refractories, precision ceramics, and third-generation semiconductors.
According to market research reports, the global silicon carbide market was valued at approximately USD 3.98 to 5.77 billion in 2025, and is projected to grow at a compound annual growth rate (CAGR) of 8.8% to 17.7% from 2026 to 2034, with the market expected to exceed USD 9.14 billion by 2032. This growth trend fully reflects the rising strategic importance of silicon carbide materials in the global industrial system.
Silicon carbide (SiC) is a compound of silicon and carbon bonded covalently. Naturally occurring silicon carbide (moissanite) is extremely rare; almost all industrial silicon carbide is synthetically produced. The classic manufacturing method involves smelting quartz sand and petroleum coke in an Acheson graphite resistance furnace at temperatures between 1600°C and 2500°C.
Silicon carbide has a Mohs hardness of 9, ranking fourth among inorganic materials, behind only diamond, boron carbide, and cubic boron nitride. Its Knoop hardness is approximately 2480 kg/mm², far exceeding that of aluminum oxide (2100 kg/mm²) and silicon (850 kg/mm²). Additionally, silicon carbide offers high thermal conductivity (up to 150-200 W/m·K), low thermal expansion coefficient, excellent chemical stability, and outstanding wear resistance.
As the most classic application, silicon carbide is widely used to manufacture grinding wheels, oilstones, mounted points, grinding segments, sandpaper, lapping compounds, and various abrasive tools due to its high hardness and self-sharpening properties. Green silicon carbide is suitable for grinding cemented carbide, hard and brittle metals, and non-metallic materials (such as gemstones, optical glass, ceramics, etc.), while black silicon carbide is widely applied in general grinding, cutting, and sandblasting. The global abrasives market reached CNY 450.625 billion in 2025, providing a solid foundation for silicon carbide applications.
With its excellent high-temperature resistance, thermal shock resistance, and chemical inertness, silicon carbide-based advanced refractories are lightweight, high-strength, and energy-efficient. Lower-grade silicon carbide (approx. 85% SiC) is an excellent metallurgical deoxidizer. In industrial furnaces, silicon carbide is widely used for refractory linings, heating elements, and wear-resistant components.
Silicon carbide ceramics, with their high strength, good oxidation resistance, and dimensional stability at high temperatures, are used in high-end applications such as gas turbine blades, wear-resistant seals, rocket nozzle components, and lightweight ballistic armor. Silicon carbide powder is also used in automotive brake pads, clutches, and other high-durability components.
High-purity silicon carbide single crystals are the core material for third-generation semiconductors, with power devices increasingly used in new energy vehicles, photovoltaic power generation, 5G communications, and other fields. Silicon carbide is also used in light-emitting diodes (LEDs) and early radio detectors. In recent years, the market growth of SiC in semiconductor substrates, power electronics, and sensors has been particularly significant.
