Silicon Slag 65

Silicon slag 65 manufacturers introduce that silicon slag is mainly composed of silicates, silica, and other components. It is produced during the manufacturing process of silicon-based materials. Silicon-based materials include Portland cement and lithium silicate batteries. These materials will produce a large amount of silicon slag during the production process.

Reduce costs associated with industrial waste disposal. The utilization of silicon slag 65 can reduce the generation of industrial waste and reduce waste treatment costs. In the production process of silicon-based materials, the generation of silicon slag is inevitable. However, if silicon slag 65 can be used efficiently, it will not only minimize waste generation but also decrease the expenses associated with waste treatment, thereby enhancing the economic viability of the enterprise.

Briquette:​ Compressed balls from silicon slag powder - zero dust, ideal for automated feeding

Custom sizing:​ Tailored to your furnace type, charging system, and dissolution requirements

Quality:​ Uniform particle distribution, low fines (<5% below nominal size), no caking, free-flowing

30-50% Cost Reduction​ - Direct factory pricing; Si65 delivers deoxidation at a fraction of FeSi 75% cost, significantly lowering your cost-per-ton of steel.

Stable Si Content (65±2%)​ - Tight composition control ensures predictable deoxidation performance, batch after batch.

90%+ Silicon Recovery​ - High elemental silicon content means efficient oxygen removal and minimal alloy waste.

Steelmaking Deoxidation:​ Primary use in BOF/EAF - substitute for FeSi 75% in carbon steel, structural steel, and low-alloy steel production

Alloying Agent:​ Si adjustment in steel and ferroalloy production

Foundry & Casting:​ Improves fluidity in gray iron and ductile iron; promotes graphitization, reduces brittleness
