Ferrosilicon Nitride 200 Mesh Powder For Refractory Additives

Ferrosilicon Nitride 200 Mesh Powder is a fine Fe-Si-N based material used as a refractory additive in taphole clay, iron trough castable, refractory castable, ramming mix and other high-temperature refractory formulas. Compared with lump material, 200 mesh powder is easier to disperse in dry mixing systems and can be matched with refractory plants that need finer particle distribution in their formulas.

You may need this product when your refractory material requires stable nitrogen-silicon input, better powder blending behavior and high-temperature performance support. In taphole clay and iron trough materials, ferrosilicon nitride can help improve formula stability under severe thermal conditions, but the actual effect depends on your full refractory formulation, binder system, carbon source, mixing method and firing or service environment.

We supply ferrosilicon nitride 200 mesh powder with controlled chemical composition and powder size according to order requirements. Before shipment, we help you confirm N, Si, O, C, Fe, particle size, moisture, packing method, COA, MSDS, shipping marks and export documents. If your refractory plant has specific limits for nitrogen, oxygen, moisture or mesh passing rate, you can send us your internal standard before quotation.

Q: What is ferrosilicon nitride 200 mesh powder used for?
A: Ferrosilicon nitride 200 mesh powder is used as a refractory additive for taphole clay, castable, iron trough materials, ramming mix and other high-temperature refractory formulas.

Q: Why choose 200 mesh ferrosilicon nitride powder?
A: 200 mesh powder has finer particle size and better dispersion in refractory mixing systems. It is suitable when your formula needs uniform powder blending and stable Fe-Si-N input.

Q: What chemical values should be checked before ordering?
A: You should check N, Si, O, C, Fe, Al, Ca, P, S, moisture and particle size by batch COA before shipment.

Q: Can the particle size be customized?
A: Yes. Besides 200 mesh powder, custom particle size can be discussed according to your refractory formula and order quantity.

Q: How is ferrosilicon nitride powder packed for export?
A: Standard export packing is usually 1MT jumbo bag with inner liner. Small bags, pallet packing, custom shipping marks, COA, MSDS and loading photos can be arranged according to order requirements.
