Product Introduction
Silicon Slag, also known as off-grade silicon or silicon by-product, is the residue left after refining industrial silicon or ferrosilicon. Despite being a by-product, silicon slag retains a high content of silicon (Si) and is widely used in the metallurgical industry due to its cost-effectiveness and functional properties. It comes in various particle sizes, typically in lump or powder form, and is suitable for use in steelmaking, foundry, and alloy production.

FAQ
Q1: Is silicon slag the same as silicon metal?
No! Silicon slag is a by-product with lower purity (30%-70% Si), while silicon metal has ≥98% Si.
Q2: How is silicon slag produced?
It's obtained during the smelting process of silicon metal or ferrosilicon, where impurities separate and form slag.
Q3: Can silicon slag replace ferrosilicon?
Partially! It's a cost-effective alternative but has lower silicon content, so adjustments in dosage may be needed.
Q4: What's the best silicon content for steelmaking?
50%-65% Si is ideal for efficient deoxidation and alloying.
Q5: How should silicon slag be stored?
Keep in a dry, ventilated place to avoid moisture absorption.
