Metallurgical Grade Silicon Carbide SiC Briquette
Reliable High-Density SiC for Industrial Steelmaking
Metallurgical-grade Silicon Carbide (SiC) briquettes are specially designed to optimize steelmaking and foundry operations. Unlike granular SiC, briquettes provide higher density, lower dust generation, and improved ease of handling. Their uniform composition ensures consistent performance in high-temperature metallurgical processes.
These briquettes are particularly beneficial for steel mills, foundries, and alloy producers seeking efficiency, stability, and reduced material loss in large-scale operations.

Industrial Applications
Electric Arc Furnace Steelmaking
SiC briquettes dissolve efficiently in molten steel, providing uniform silicon content and deoxidation. Their dense structure reduces dust loss during feeding, enhancing yield and reducing operational cost.
Foundry Iron Production
In grey and ductile iron casting, SiC briquettes improve graphite morphology and reduce oxide inclusions. The controlled release of silicon ensures better metal structure and fewer defects in the final casting.
Ferroalloy Production
High-density briquettes allow precise control of alloy composition. Low dust generation reduces contamination risks and supports compliance with strict industrial standards.
Metallurgical Mechanism
When added to molten metal, SiC briquettes release silicon and carbon gradually. Silicon acts as a powerful deoxidizer, while carbon assists in reduction reactions. The briquette form ensures slow and uniform dissolution, reducing slag formation and minimizing SiC losses compared to granular forms.
This makes them highly effective in maintaining consistent steel or iron chemistry and enhancing metallurgical efficiency.
Advantages Over Granular SiC
| Feature | Briquette | Granular SiC |
|---|---|---|
| Dust Loss | Very low | High |
| Handling | Easy | Medium |
| Uniformity | Excellent | Variable |
| Dissolution Rate | Controlled | Fast, uneven |
| Cost Efficiency | Higher long-term | Lower upfront |
Recommended Usage
SiC briquettes are generally added during the refining or deoxidation stage, depending on furnace type and production goals. Typical dosing ranges from 0.4% to 1.0% of total charge. Their high density ensures minimal segregation and uniform distribution in the molten bath.
Available Sizes and Forms
