Uses

Ferrosilicon nitride NITRO-FESIL^® N30 is new material, which designed as 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.

Description

Ferrosilicon nitride NITRO-FESIL^® N30 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-silicon nitride is not formed.

NITRO-FESIL^® N30 is obtained by nitriding of mixture of high grade ferrosilicon alloys and metallic silicon. Ferrosilicon nitride NITRO-FESIL^® N30 differs from the traditional «furnace» ferrosilicon nitride in special composition structure based on β-Si₃N₄.
