Silicon Metal 331

Silicon metal is is a metallurgical material made of quartz(SiO2) and coke reduced by high temperature smelting in an electric furnace,The main compoment Si content is usually about 98% and high purity products can reach 99.99%.Its impurities are mainly Fe, Al, Ca and so on.

Size: 10-100 mm, 3-10mm, 0-3mm or as customers' requirements.

Packing: 25Kg/bag, 1MT/bag or as your requirements.

Remark: chemical composition and size can be optimized by the customers' requirements.

1.The "Sweet Spot" Grade​ - 10-20% cheaper than 3303/421 while delivering Fe/Al/Ca purity that 441 cannot match .

2.Protects Catalyst Life (Organosilicon)​ - Al≤0.3% minimizes catalyst poisoning in silicone oil/rubber/polymer synthesis, improving reaction stability and product transparency.

3.Stronger, Cleaner Aluminum Alloys​ - Tight Fe/Al control prevents brittle needle-like phases in aerospace & automotive castings; improves strength and toughness.

4.Stable Si Content (≥99%)​ - Fluctuation within ±0.3%; no formula recalibration needed batch-to-batch.

5.Versatile Forms​ - Lump for smelting, granules for dosing, powder for chemical reactors-one grade, three supply formats.

6.Cost-Effective Deoxidizer​ - For steel mills, 331 offers cleaner deoxidation than 553/441 at a fraction of the cost of 3303.

7.Full Traceability​ - Every batch tagged with production date, furnace lot, and ICP verification report.
