What Is Silicon Briquette?

Silicon briquette is a pressed block made from ferrosilicon fines and a binder, supplied at 65-75% Si. Briquetting turns a by-product into a dense, uniform charge material instead of loose fines.

Bright Alloys presses 30x30x50 mm silicon briquettes as a substitute for part of the lumpy ferrosilicon charge, with carbon and aluminium at ≤2.0% and sulphur and phosphorus at ≤0.05%.

Applications and Performance

Steelmaking Deoxidation

Silicon briquette carries silicon into the heat in a dense form, so the charge can include less lumpy ferrosilicon.

Foundry Nodulizing and Alloying

In iron foundries the briquettes serve as a silicon carrier for nodulizing and alloy addition, dissolving evenly in the melt.

Slag Conditioning

Uniform block size makes the addition easier to control than loose fines, which helps keep slag condition stable through the heat.

Silicon Briquette FAQs

How much can I save by switching to silicon briquette? +

For a 400,000 ton/year plant, replacing FeSi72 with silicon briquette 70 can save over $1.3 million annually on alloy costs alone. In EAF operations, additional electricity savings (up to 1,800 kWh/ton of briquettes) can double the benefit. See detailed cost model →

Can I use silicon briquette in my existing furnace without new equipment? +

Yes – zero capital investment required. Silicon briquettes use the same charging chutes, hoppers, and manual addition methods as FeSi. Their 30×30×50mm pillow shape fits all standard equipment. You can switch from one heat to the next with no process modifications. Learn about phased trial →

What is silicon briquette? +

Silicon briquette is a ferroalloy pressed into oblate spheroidal briquettes (typically 30x50mm) used in steelmaking for deoxidation and carburization. It contains high silicon (60-80%) with controlled carbon, phosphorus, and sulfur. See our Si 70% briquette for typical composition.

What grades of silicon briquette are available? +

We supply three main grades: Silicon Briquette 75% (high purity for critical deoxidation), Silicon Briquette 70% (standard grade), and Silicon Briquette 65% (cost-effective with lower Si). Custom compositions are also available upon request.

How do I get a price for silicon briquette? +

Prices vary with grade, order volume, and current ferroalloy market conditions. For the latest quote, please visit our contact page or submit an inquiry through our quote form. Typical lead time is 10-15 days.

Is quality certification available for silicon briquette? +

Yes, all our silicon briquette products are manufactured under ISO 9001:2015 certified processes. Third-party inspection by SGS, BV, or Intertek is supported. Request our quality control report for detailed chemical analysis.
