Abrasive Grade Silicon Carbide Grain and Micropowder
Quick Answer: Our silicon carbide abrasive range includes grain sizes from 12–220 and micropowder from 240–4000, with SiC content from 96% to 98% according to the current specification.
For purchasing, confirm the required SiC content, grit size, free carbon, Fe2O3 limit, magnetic material content, quantity and packing before quotation.
Silicon carbide is a hard industrial material used in abrasive, refractory and metallurgical applications. For abrasive-grade material, particle-size distribution and impurity control are especially important because they affect grinding performance, surface finish and product consistency.

Key Properties of Silicon Carbide
High Hardness
Silicon carbide is a hard abrasive material suitable for grinding, cutting, surface treatment and wear-resistant applications.
Good Thermal Stability
SiC maintains useful physical properties under high-temperature industrial conditions, supporting applications in refractory and metallurgical processing.
Controlled Particle Size
Different grain and micropowder specifications allow the material to be selected according to the required grinding, polishing or processing accuracy.
Stable Chemical Composition
For repeat industrial use, SiC content, free carbon, iron oxide and magnetic material limits should remain within the agreed specification.

How to Choose Silicon Carbide Grit Size
The suitable silicon carbide size depends on the required material-removal rate and surface finish.
| Specification |
Selection Focus |
| 12–80 |
Coarser abrasive grains for higher material-removal requirements |
| 90–150 |
Medium abrasive grain range for controlled grinding applications |
| 180–220 |
Finer abrasive grain for processes requiring a finer surface finish |
| 240–4000 |
Micropowder range for fine grinding, polishing or precision processing |
If your process requires a specific particle-size distribution rather than only a nominal grit number, include the complete size requirement in your inquiry.

Silicon Carbide Applications
Abrasive Processing
Silicon carbide grain is used in grinding, cutting and surface-treatment applications where high hardness and controlled particle size are required.
Fine Grinding and Polishing
Micropowder grades can be selected for finer processing where smaller particle sizes and controlled surface finish are important.
Refractory Materials
Silicon carbide can also be used in refractory formulations where thermal stability and wear resistance are required.
Metallurgical Applications
Other silicon carbide grades can be used as silicon- and carbon-bearing additions in metallurgical processes. The suitable chemistry should be selected separately from the abrasive-grade specification shown on this page.
How to Compare Silicon Carbide Quotations
Do not compare two silicon carbide offers only by price per ton. Before comparing prices, confirm that both quotations use the same:
- SiC content
- Grit or micropowder specification
- Free carbon limit
- Fe2O3 limit
- Magnetic material requirement
- Packing
- Inspection requirements
Different grit sizes and chemistry limits can result in different quotations even when the product is generally described as silicon carbide.
