Si3n4 Ferrosilicon Nitride

Product Overview

Si₃N₄ Ferrosilicon Nitride is a high-performance metallurgical material composed mainly of silicon nitride (Si₃N₄) combined with ferrosilicon. It is produced through controlled nitriding processes that introduce nitrogen into silicon-rich alloys, forming stable nitride phases.

This material is widely used in steelmaking, refractory systems, and advanced foundry applications where nitrogen alloying, thermal stability, and controlled silicon addition are required. Compared with conventional ferrosilicon or silicon powder, Si₃N₄ Ferrosilicon Nitride provides higher nitrogen efficiency and more stable metallurgical behavior.

ZhenAn supplies industrial-grade Si₃N₄ Ferrosilicon Nitride designed to meet the performance demands of modern metallurgical processes.
