Silicon Briquette – Top Questions from Steelmakers

What is a silicon briquette and how does it cut alloy costs so dramatically? +

A silicon briquette (Si≥70%) is a pressed pillow‑shaped product made from high‑purity silicon byproducts and a proprietary inorganic binder. It replaces expensive ferro silicon (FeSi), aluminum, and SiC in three key areas: ladle deoxidation (85‑90% recovery), EAF cold charging (provides chemical energy, saving ~1,800 kWh/ton of balls), and LF slag reduction (cuts FeO without carbon pickup). At ~$600/ton vs FeSi at $1,300/ton, it delivers silicon at half the cost per effective kilogram, leading to over $1.3 million annual savings for a typical 400,000 tpy plant.

Does switching to silicon briquette require new equipment or process changes? +

Absolutely none. Silicon briquettes use the same charging chutes, hoppers, and manual addition methods as traditional ferro silicon. Their 30×30×50mm pillow shape is engineered for standard handling equipment. You can transition from one heat to the next with zero capital investment — it’s simply a change of the material being added. Our phased trial (10% → 30% → 50% substitution) lets you verify performance without risk.

How do I get samples and start a trial in my plant? +
