Nitride Ferro Silicon

Product Description:
The main composition of Ferro Silicon Nitride is Si3N4,along with free iron, no-nitride Ferro Silicon and other mixture. It mainly has two forms:powder and granule. 

1.Nitride ferro silicon powder is an important raw material for the production of tap-hole clay for blast furnaces, has an outstanding feature of sintering-supporting,anti-erosion, low-cost.
2.Nitride ferro silicon granule is used for deoxidation and alloying element as alternative to Fesi, providing nitrogen source with an inexpensive alloy.
