Ferrosilicon Nitride

Ferro Silicon Nitride is a composite material composed of silicon, nitrogen, and iron. It combines the high-temperature resistance of refractories with the properties of an alloy additive. It is widely used in the refractory industry and steelmaking sector as an efficient reinforcing phase for refractories and a source of nitrogen.

Ferro Silicon Nitride is primarily produced by the direct nitridation method. Ferrosilicon powder is subjected to a prolonged nitriding process in a high-temperature (typically 1100-1400°C) nitrogen atmosphere. This allows silicon to react with nitrogen to form a stable Si3N4 phase, bonded with iron. The final product is obtained after cooling, crushing, and screening.

​

Refractories:​​ A key additive for blast furnace taphole clay and trough castables. Its high-temperature strength, erosion resistance, and透气性 significantly extend refractory service life.

Steelmaking Industry:​​ Production of high-nitrogen steel, weathering steel, silicon steel sheets, etc.

​Cast Iron:​​ Serves as an inoculant to refine graphite structure and improve the properties of cast iron.

​Excellent Refractoriness:​​ Stable structure with exceptional resistance to oxidation and slag erosion.

​Efficient Nitrogenation:​​ As a steelmaking additive, it increases the nitrogen content in molten steel stably and controllably.

​Enhanced Wear Resistance:​​ Significantly improves the strength, hardness, and wear resistance of steel.
