Silicon carbide (SiC) is an important material widely used in metallurgical industries such as steelmaking and foundry production. Metallurgical silicon carbide is commonly used as a deoxidizer, carburizer, and additive in steel production.
Compared with high-purity silicon carbide used in abrasives and ceramics, metallurgical silicon carbide usually contains less than 90% SiC and is specifically designed for industrial metallurgical processes.
What Is Metallurgical Silicon Carbide?
Metallurgical silicon carbide refers to silicon carbide materials used in steelmaking, casting, and other metallurgical processes.
It is produced through high-temperature smelting of silica and carbon materials in electric furnaces.
Because of its unique chemical composition, silicon carbide can function as:
- a deoxidizer
- a carburizing agent
- a metallurgical additive
This makes it widely used in electric arc furnace steelmaking and cast iron production.
Chemical Composition of Metallurgical Silicon Carbide
The chemical composition of silicon carbide may vary depending on grade and application.
Typical composition includes:
These grades are widely used in steelmaking and foundry industries.
Particle Size Specifications
Silicon carbide used in metallurgical applications is usually supplied in various particle sizes depending on furnace requirements.
Common sizes include:
- 0–10 mm
- 1–10 mm
- 1–3 mm
Customized sizes can also be produced according to customer specifications.
Particle size plays an important role in metallurgical reactions because it affects dissolution speed and reaction efficiency in molten steel.
Why Silicon Carbide Below 90% Is Widely Used
Silicon carbide used in metallurgy usually has a purity below 90%. This grade offers a balance between cost and metallurgical performance.
Unlike abrasive-grade silicon carbide, metallurgical silicon carbide is optimized for large-scale industrial processes.
Key advantages include:
- lower production cost
- efficient deoxidation performance
- stable metallurgical reactions
Because of these benefits, metallurgical silicon carbide is widely used in steel mills worldwide.
