Ferro Silicon Nitride, also known as Fe-Si3N4, which is mainly contains Si3N4 - Silicon Nitride, along with Free Iron, Non-nitride Ferro Silicon and small amount of other compounds. Refractory used Ferro Silicon Nitride is gray-white (or dark brown) powder. Steel making grade Ferro Silicon Nitride is gray-white granular material.Ferro Silicon Nitride is a new excellent refractory materials, which can replace the expensive Silicon Nitride to be used for Taphole Clay of large blasting furnace.


Ferro Silicon Nitride is an alloy additive in smelting of cold-rolling orientated silicon steel. Its addition increases the steel strength of ambient low temperature and improves corrosion-resistance, thermal shock resistance and abrasion resistance abilities of steels.Ferro Silicon Nitride is new excellent refractory materials, which can instead of expensive Silicon Nitride, used for no water gunning materials in steel plant.


    Ferro Silicon Nitride powder is mainly used in Taphole Clay of large blasting furnace.
    Ferro Silicon Nitride powder can also be used in Iron Trough or other Castable Refractories.
    Ferro Silicon Nitride for steel making is mainly for oriented silicon steel, stainless steel, heat-resistant steel, corrosion-resistant steel, alloy steel or other nitrides steel, like HRB400 rebar.
Ferro Silicon Nitride is also an additive agent of making Cold rolled unidirectional silicon steel sheets.
