Ferrosilicon Nitride For Refractory Materials

    Ferrosilicon Nitride for Refractory Applications Ferrosilicon Nitride is a high-performance additive widely used in refractory materials. It contains silicon nitride phase(Si₃N₄), which provides excellent resistance to high temperature, thermal shock, corrosion, and wear. When added to refractory products, Ferro Silicon Nitride helps improve their strength and durability under harsh working conditions. Ferrosilicon Nitride is commonly used in blast furnace taphole clay and Al₂O₃-SiC-C based refractories. It helps extend the service life of refractory products and improves their performance during long-term operation. According to different application requirements, we offer standard grade ferrosilicon nitride and high nitrogen grade ferrosilicon nitride. Customers can choose suitable grades based on their production needs.   Specification Content (%) Si3N4 N Si Fe Al + Ca Standard 70-75 28-30 47-51 12-15 <2.5 High-Nitrigen 75-80 30-33 49-53 12-16 <2.5   Form: Powder…
