Cov txheej txheem ntau lawm ntawm ferrosilicon nitride yog txawv. Ntxiv nrog rau cov ntsiab lus ntawm impurities nyob rau hauv raw ferrosilicon nws tus kheej, ntau yam binders ntxiv thaum lub sij hawm tsim khoom, uas inevitably qhia ntau yam impurities. Resin feem ntau yog siv los ua ib daim ntawv khi. Thaum siv cov resin los ua cov ntawv khi, cov seem ntawm cov pa roj carbon monoxide thiab sulfur yog qhov siab. Thaum siv lwm cov binders, tag nrho cov nqi ntawm impurities qhia feem ntau yog tswj tsis pub dhau 1%.
Hauv cov txheej txheem tsim khoom ntawm ferrosilicon nitride, ferrosilicon yog siv los ua qhov hnyav hnyav kom tau txais cov khoom tsim nyog uas muaj 30% nitrogen nrog tag nrho qhov hnyav ntawm 50% (piv txwv li: 30% nitrogen + 2.5% oxygen + 1} % binder residue). Qhov kwv yees cov ntsiab lus ntawm txhuas thiab calcium yog 1.33% thiab 1%, feem.
Cov kev txwv sab saud rau cov ntsiab lus txhuas thiab calcium hauv tus qauv yog 1.5% thiab 1%. Cov txheej txheem tsim khoom ntawm ferrosilicon nitride yog qhov kub thiab txias thiab tsis muaj dej noo. Thaum lub sij hawm ua tiav cov khoom tiav, cov khoom tsim nyog yuav tsum tau muab ntim thiab ntim kom tsis txhob muaj qhov nqus ntawm cov dej noo hauv cov huab cua, vim ferrosilicon nitride hmoov feem ntau yog siv rau hauv cov ntaub ntawv uas tsis yog dej-txog refractory. Tus qauv qhia tias H2O<0.1%.
