High Purity FeSi 75 Lump Material

 

When you choose a high-purity FeSi 75 lump, the key questions are simple: Will the chemistry stay consistent from batch to batch, will the material behave predictably in the furnace, and will the impurity limits match your internal control targets.

This grade is designed for stable silicon contribution with a cleaner chemistry profile, so your team can manage refining work with fewer corrective additions.

The lump format (50–100 mm) is selected for reliable handling strength and steady charging, helping reduce breakage during loading and keeping feed behavior consistent.

For cost control, the main value comes from utilization efficiency: predictable reaction behavior reduces waste, rework, and unexpected consumption.

 

 

Parameter	Typical Value	Buyer Benefit
Silicon (Si) Content	75%	Ensures consistent silicon input
Aluminum (Al) Content	≤ 0.5%	Fosters cleaner melting performance
Maximum Sulfur (S)	≤ 0.02%	Minimizes disruptions during processing
Maximum Phosphorus (P)	≤ 0.04%	Enhances stability of final products
Particle Size Range	50–100 mm	Enables precise furnace charging control
Packaging Specification	1000 kg Jumbo Bags	Guarantees moisture-proof transportation

 

 

Q：How do you keep high purity consistency
A：Each batch is tested for Si accuracy and impurity limits, with size screening to maintain consistent lump quality.

Q：What delivery time should we plan for
A：Standard delivery is usually 15–20 days depending on destination and shipping schedule.

Q：What support do you provide after ordering
A：We provide batch documentation, packing confirmation, and technical guidance on addition planning when needed.
