Cov txheej txheem smelting thiab kev tsim khoom ntawm ferrosilicon nitride feem ntau cuam tshuam nrog ntau yam txheej txheem. Cov txheej txheem no koom nrog ntau cov ntsiab lus. Hauv qab no yog cov lus qhia luv luv rau kev tsim cov ntsiab lus ntawm ferrosilicon nitride. Koj tuaj yeem xa mus rau cov ntsiab lus no thaum smelting. .
Siv ferrosilicon alloy FeSi75 ua raw khoom, lub tshuab nitridation ntawm flash combustion synthesis ntawm ferrosilicon nitride tau kawm. Cov txiaj ntsig tau pom tias thaum lub sij hawm nitriding txheej txheem, silicon yog thawj oxidized, thiab silicon yog oxidized los ua gaseous SiO, uas txo cov pa ib feem ntawm lub zog. Thaum cov pa oxygen ib nrab siab p (O2) Tsawg dua lossis sib npaug ntawm 10–20MPa (T=1823K), Si thiab N2 (g) reacts ncaj qha rau hauv daim ntawv silicon nitride, thiab roj SiO2 nws thiaj li tshwm sim nrog N2 (g) los ua silicon nitride.
FeSi2 thiab Fe0.42Si2.67 hauv ferrosilicon alloy FeSi75 tsis txhawb kev tsim ntawm silicon nitride, thiab hnov mob nrog silicon uas tsis koom nrog nitridation cov tshuaj tiv thaiv rau Fe3Si. Cov theem tseem ceeb ntawm ferrosilicon nitride yog silicon nitride thiab Fe3Si, uas muaj ntau ntau ntawm columnar silicon nitride. Fe3Si yog qhwv los ntawm columnar Si3N4 thiab nyob rau hauv ib qho kev sib cais.
