High Quality Silicon Slag

Silicon slag is a by-product of silicon metal and ferro silicon production, containing a high percentage of silicon along with other elements such as calcium, aluminum, and iron. It is widely used in steelmaking and foundry industries as a cost-effective substitute for ferro silicon. Silicon slag provides excellent deoxidation and desulfurization performance, helping reduce production costs while maintaining metallurgical quality.

Silicon Content (Si): 40% – 75%

Carbon (C): ≤ 8%

Sulfur (S): ≤ 0.05%

Phosphorus (P): ≤ 0.05%

Size Range: 10–50mm, 10–100mm (customized sizes available)

Packing: Jumbo bags or customized packaging

Silicon slag has become increasingly popular worldwide because of its competitive price-performance ratio. It serves as an economical alternative to ferro silicon, offering comparable metallurgical benefits at a lower cost. Its flexibility in applications-from deoxidation in steelmaking to inoculant use in foundry processes-makes it attractive to global buyers seeking efficiency and cost savings.

Yes. Silicon slag effectively enhances alloy recovery by reducing oxidation losses during steelmaking. The silicon content in the slag provides strong deoxidizing power, ensuring better utilization of alloying elements and improving steel quality. This translates into reduced waste, higher yield, and lower overall production costs.

Purchasing silicon slag directly from the factory provides several advantages:

Stable Quality Control: Direct monitoring of raw materials and production.

Lower Costs: No middlemen, ensuring the most competitive prices.

Customized Specifications: Sizes and grades tailored to customer requirements.

Reliable Supply: Consistent stock availability for long-term projects.

Professional Support: Technical guidance and after-sales service from the manufacturer.
