Ferrosilicon NitrideUses

Ferrosilicon nitride NITRO-FESIL® N25 is new material, which designed for alloying by nitrogen a wide range of steels, such as transformer, stainless, structural, etc. Ferrosilicon nitride NITRO-FESIL® N25 is produced by SHS-technology (combustion synthesis) and has unique combination of service properties.


NITRO-FESIL® N25 is composition material based on beta-silicon nitride (β-Si3N4). It is synthesized in special reactors under pressure 10 MPa and temperature about 2000 °C. Because of a high combustion temperature, α-nitride of silicon is not formed.

NITRO-FESIL ® N25 is produced by nitriding of ferrosilicon 65 % and 75 % alloys. It is characterized by minimum content of oxygen, hydrogen, sulfur and other impurities. Due to the high temperature of the process, the material produced is of high strength.
