Ferrosilicon nitride NITRO-FESIL® N30 designed as a component for refractory production, mainly as a strengthener in tap hole muds and runner clays. NITRO-FESIL® N30 is produced by SHS-technology (combustion synthesis) and has unique combination of service properties.

It is synthesized in special reactors under pressure 10 MPa and temperature about 2000 °C. Ferrosilicon nitride NITRO-FESIL® N30 differs from the traditional «furnace» ferrosilicon nitride in special composition structure based on beta-Si3N4.
