What is SiC 85–90% Lumps (6–25 mm) Used For?
Silicon carbide (SiC) with 85–90% content in lump form (6–25 mm) is a widely used metallurgical material, offering high hardness, thermal stability, and cost-effectiveness. It is primarily employed in steelmaking, ferroalloys, foundries, and refractory applications, where bulk addition of carbon and silicon is required. Industrial procurement managers, process engineers, and technical decision-makers can benefit from understanding its main applications.
Key Characteristics of 85–90% SiC Lumps
SiC content: 85–90%
Size: 6–25 mm, ideal for bulk feeding
Form: Lumps allow controlled gradual melting
Purity: Sufficient for metallurgical applications
Hardness: High, suitable for refractory use and wear resistance
These properties make 85–90% SiC lumps cost-effective and reliable for large-scale industrial processes.
Typical Applications
1. Steelmaking
Used as a deoxidizer and carbon source in electric arc furnaces (EAF) and induction furnaces
Contributes to silicon and carbon content adjustment in steel
Supports bulk metallurgical operations with predictable chemical reactions
2. Ferroalloy Production
Supplies carbon and silicon for producing ferro-silicon and other silicon-containing alloys
Lumps are suitable for large furnace feedings, ensuring even chemical distribution
3. Foundry and Cast Iron Applications
Adjusts carbon content and improves fluidity and surface finish in cast iron
Reduces oxide inclusions in molten metal
4. Refractory Industry
Used in refractory bricks, castables, and high-temperature furnace linings
Provides wear resistance and thermal stability in kilns and crucibles
5. Bulk Industrial Processes
Ideal for operations requiring gradual dissolution and long-term furnace charging
Efficient for large-scale, cost-sensitive metallurgical operations

Frequently Asked Questions (FAQ)
Can 85–90% SiC lumps be used in small furnaces?
They are mainly suited for large furnaces; for small-scale operations, 3–6 mm granules or coarse powders are preferred.
How does lump size affect reaction rate?
Larger lumps dissolve slower, providing gradual carbon and silicon addition, ideal for bulk metallurgical operations.
Are 85–90% SiC lumps suitable for specialty steels?
Yes, but for high-purity steels or precision applications, higher-grade SiC (95% or above) may be preferred.
What industries benefit most from this form?
Steelmaking, ferroalloy production, foundries, and refractory manufacturing.
