Silicon Briquette: an overview | Best Price & Quality Supplier
What is Silicon Briquette?
Silicon briquette is an alloy material primarily composed of Si, Fe, Al, Ca, and Mg. It has a flattened spherical appearance, with a size ranging from 10 mm to 50 mm. Due to its spherical resemblance, some people also refer to silicon briquette as "silicon ball." Silicon slag and silicon metal slag are the main raw materials for producing silicon briquette. By grinding these smelting slags into powder and mixing them with different alloy powders, a glass water binder is used in a specialized briquetting machine to shape the mixture. To reduce impurities in the silicon briquette, they are typically calcined at 1500°C. Silicon briquette can be categorized into ferro silicon briquette, silicon metal briquette, silicon carbide briquette, silicon carbon briquette, and carbon briquette. Given their alloy-like properties, the chemical composition can be adjusted according to application needs, providing considerable flexibility.
Production Process of Silicon Briquette
As a new type of alloy material, many are unaware of how manufacturers produce silicon briquette. The main raw materials for silicon briquette come from silicon slag. Ferro silicon slag and silicon metal slag undergo professional laboratory testing and manual screening before being finely ground into powders of 1 to 10 um using ultra-fine grinding equipment, followed by filtration through screens. The ground material is then mixed with various alloy powders as per the required ratios, calculated through strict professional standards. The blended alloy powder uses glass water as a binder and is shaped by a briquetting machine before being air-dried. To minimize impurities in the silicon briquette, manufacturers typically perform high-temperature calcination, effectively reducing internal impurities and harmful elements. After calcination, the temperature of the silicon briquette is maintained at 800°C, and they are packaged and stored in ton bags after cooling.

Sustainable
As competition in the steel market intensifies, reducing production costs and enhancing efficiency has become a focus for manufacturers. Research shows that most steel mills use fero silicon to raise the temperature of converter steel, meeting the current high scrap steel ratio requirements. While ferro silicon is commonly used and effective in steelmaking, some mills have become overly reliant on it. Compared to silicon briquette, the price of ferro silicon is higher and more volatile, putting greater cost pressure on steel enterprises. As an economical metallurgical material, silicon briquette have gained widespread attention since their introduction. They can replace some ferro silicon and silicon metal, effectively lowering production costs and enhancing profits for manufacturers. As steelmaking technology continuously improves, the demand for silicon briquette rises annually, making them essential metallurgical materials in various steelmaking processes.
