What are the advantages of using 10-100mm Ferro Silicon Nitride granules in foundries?

Ferro Silicon Nitride (FeSiN) granules in the 10-100mm size range​ are highly valued in foundry operations​ for their optimal handling characteristics, controlled reactivity, and efficient melting performance. This mid-to-large granule size​ strikes an ideal balance between ease of use​ and effective reaction in molten metal.

Granules within this range are easy to convey, store, and dose mechanically, reducing labor intensity and minimizing material waste. Their size also helps prevent excessive dust generation, which is a common issue with finer powders, thus contributing to a safer and cleaner working environment. Moreover, the gradual dissolution​ of 10-100mm FeSiN granules in molten iron ensures uniform distribution of silicon nitride (Si₃N₄)​ and controlled nitrogen release, leading to better nodule formation in ductile iron.

These granules are extensively used as nodulizers, inoculants, or alloying agents​ to improve the microstructure and mechanical properties​ of cast iron and steel. The presence of Si₃N₄​ enhances high-temperature performance, while the ferro component​ contributes to slag formation and alloy stability.
