Menene Ferrosilicon Nitride?
Ferrosilicon nitridewani hadadden abu ne na silicon nitride, iron da ferrosilicon. Yawancin lokaci ana yin shi ta hanyar nitridation kai tsaye na ferrosilicon alloy FeSi75 a babban zafin jiki. Yawan juzu'i na Si3N4 ya kai 75% ~ 80%, kuma yawan juzu'in Fe ya kai 12% ~ 17%. Babban matakansa sune α-Si3N4 da β-Si3N4, ban da wasu Fe3Si, ƙaramin adadin α-Fe da ƙaramin adadin SiO2.
