Silicon carbide powder is a fine, granular form of silicon carbide (SiC), a compound made of silicon and carbon atoms. Known for its exceptional hardness, thermal resistance, and chemical stability, this powdered form is a go-to material across various industries.
The recent surge in demand for electric vehicles (EVs), 5G technology, and sustainable energy systems has positioned silicon carbide powder as a material of the future.
The chemical formula of silicon carbide is SiC, consisting of one silicon atom bonded to one carbon atom. These atoms form strong covalent bonds that make the compound extremely hard.
Silicon carbide powder is typically produced using the Acheson process, reaction bonding, and sintering methods.
Advanced processes include sol-gel synthesis, plasma vaporization, and chemical vapor deposition (CVD).
Used in abrasives and foundries, with minor impurities.
Used in semiconductors and ceramics, refined to remove contaminants.
| Property | Value |
|---|---|
| Thermal Conductivity | Up to 490 W/m·K |
| Electrical Resistivity | 10⁵ – 10⁶ ohm·cm |
| Melting Point | ~2,730°C |
Used in mechanical seals, nozzles, bearings, armor, and wear-resistant equipment.
Forms sintered components and wafers for LEDs and power electronics.
Enhances lithium-ion batteries and fast-charging EV systems.
Acts as a deoxidizer and improves metal purity in steelmaking.
Non-toxic but can irritate lungs—requires respirators and dust control.
Stored in airtight, moisture-controlled containers.
Demand rising in Asia-Pacific and North America; prices range from $800 to $5,000/ton depending on grade.
High-performance with cost and handling drawbacks.
Silicon carbide powder is a transformative material with applications across industries. Its combination of strength, conductivity, and efficiency makes it indispensable for the future of technology.
