Get high-purity silicon carbide powder from F320 to F1200 grit. Ideal for grinding, ceramics, and metallurgy. Certified Chinese manufacturer with fast global shipping.
Silicon carbide powder is a high-performance synthetic material composed of silicon and carbon. As one of the hardest industrial abrasives (Mohs 9.1), it is widely used for grinding, polishing, ceramic reinforcement, and metallurgical applications. Our black silicon carbide powder, available from F320 to F1200 grit, offers excellent thermal conductivity, oxidation resistance, and mechanical strength, making it ideal for high-precision and high-temperature use cases.
Superior performance in processing hard materials like metals, ceramics, and stones.
Improves the stability and durability of the product under thermal stress..
Reduces the risk of cracks and deformation in high-temperature environments.
Long-lasting performance in abrasive applications such as blasting and surface finishing.
We supply two main types of silicon carbide powder based on color and purity:
We also distinguish by grain size:
| Property | Silicon Carbide | White Fused Alumina | Boron Carbide |
|---|---|---|---|
| Mohs Hardness | 9.1 | 9.0 | 9.5 |
| Thermal Conductivity | High | Medium | Low |
| Cost | Medium | Low | High |
| Typical Use | Grinding, Ceramics | Polishing, Sandblasting | Armor, Nozzles |
Choosing the right SiC powder depends on your application:
One of our clients in Europe—a precision ceramics manufacturer—uses our F800 and F1000 silicon carbide powder in the production of ceramic valve components for the chemical industry. The consistent grain size and purity of our powder allowed them to reduce rejection rates by 18% compared to a previous supplier.
Another client in Southeast Asia sources F600 black SiC powder for photovoltaic panel edge polishing, citing lower wear on diamond tooling and better gloss levels after processing.
| Component | Content (%) |
|---|---|
| SiC | ≥98.5% |
| Fe2O3 | ≤0.20% |
| F.C (Free Carbon) | ≤0.30% |
| Moisture | ≤0.1% |
We can offer 1MT/25Kg Woven plastic bags, and 25Kg Paper bags.
Our Black Silicon Carbide is carefully handled during storage and transportation to preserve the quality of our product in its original condition.
It is used in abrasive tools, ceramic reinforcement, polishing compounds, and high-temperature metallurgical additives. Common industries include solar glass, automotive, aerospace, and advanced ceramics.
F600 has a coarser particle size than F800 and is typically used for medium polishing or rough lapping. F800 is better suited for fine finishing and achieving tight tolerances on ceramic or metal surfaces.
All production batches are analyzed for particle size distribution (via laser diffraction), chemical composition (XRF analysis), and moisture content. Retained samples are stored for quality tracking over 12 months.
Yes, we offer customized milling services for clients needing SiC powder below 1 micron for electronics, composite materials, or additive manufacturing applications.
Black SiC is tougher and more cost-effective—suitable for heavy-duty grinding. Green SiC is purer and sharper, ideal for polishing hard alloys, glass, and semiconductors.
Founded in 2005, our company is a leading manufacturer of high-quality Silicon Carbide (SiC) and various types of fused alumina products. With nearly two decades of industry expertise, we have established a reputation for delivering durable and performance-driven materials for a wide range of applications, including abrasives, refractories, and ceramics.
