Atomised Ferrosilicon Powder 15% & 45%
Atomised Ferrosilicon Powder is produced by melting and spraying FeSi into round, uniform granules instead of crushing it - which is where the low dust and predictable dissolution come from. Available in 15% and 45% silicon grades, sized 0-3 mm or 1-5 mm, it covers everything from routine alloy correction to dense-media separation in HMS plants.

Product Overview
Standard crushed ferrosilicon comes out irregular — sharp edges, uneven sizing, and a share of fines that just turns into dust on the shop floor. Atomising solves that at the source: molten FeSi is sprayed into a controlled atmosphere and solidifies as round, dense granules before it's ever screened, so what reaches you dissolves at a predictable rate and moves cleanly through pneumatic and gravity feed systems.
The 45% grade carries the silicon and density for strong deoxidation and for dense-media separation, where consistent sink-float behavior is the whole point. The 15% grade runs lighter, built for routine alloy correction and slag conditioning where a smaller silicon input is the better fit.
Production runs across our Eurasia network, with multi-stage magnetic separation and batch-by-batch QC before anything ships, and a certificate of analysis included with every order.
Industrial Power Grade
Full-density 45% granules built for heavy-duty deoxidation and dense-media circuits, where sink-float consistency matters more than anything else.
Precision Casting Grade
Tight sizing and low aluminum pickup for foundries running automotive and precision parts, where a stray inclusion means a rejected casting.
Universal Application Grade
The 15% powder covers everyday alloy correction, slag conditioning and general steelmaking additions — the workhorse grade for routine furnace operations.
Engineered Custom Grade
Need a particle band or silicon window outside our standard 0-3 mm / 1-5 mm split? We size and blend to your furnace or DMS circuit's spec on request.

Frequently Asked Questions
What is Atomised Ferrosilicon Powder?
It's ferrosilicon produced by melting and atomising the alloy into round, uniformly sized granules rather than crushing it. That gives more consistent particle shape, far less dust, and more predictable dissolution than standard crushed FeSi.
What are the main uses of Atomised FeSi?
- Steelmaking as a deoxidizer
- Foundry alloy adjustments
- Heavy-media separation (HMS) in mining
- Slag control and melt refinement
- Production of specialty alloys
What is the difference between FeSi 45% and FeSi 15%?
FeSi 45% carries more silicon and higher density, used for strong deoxidation and for dense-media separation where density is the deciding factor. FeSi 15% is the more economical option, used for controlled silicon input and slag conditioning.
Why do steel plants prefer atomised (granulated) FeSi?
Granulated FeSi generates very low dust, dissolves at a predictable rate, holds a uniform grain size, and runs more efficiently through handling systems — which translates into lower consumption for the same result.
What particle sizes are available?
The standard sizes are 0-3 mm and 1-5 mm. Custom sizing is available on request depending on the buyer's requirements.
Conclusion
Atomised Ferrosilicon Powder is the practical answer when crushed material's uneven sizing and dust just aren't good enough — for steelmaking, foundry work, or a DMS circuit that lives and dies by consistent density. Produced across the Eurasia network, it ships with the documentation and QC record that let you check it against spec the moment it arrives.
Direct-from-manufacturer pricing and steady multi-site production are why steel plants and mineral-processing operations keep coming back to us for their FeSi powder supply.
