Ferrosilicon nitride yog sib xyaw ntawm Si3N4 ua cov khoom tseem ceeb, nrog rau cov hlau dawb, tsis muaj ferrosilicon thiab ib qho me me ntawm lwm cov khoom. Ferrosilicon nitride rau refractory yog grey-dawb hmoov, thiab ferrosilicon nitride rau steelmaking yog grey-dawb granular. yam. Powdered ferrosilicon nitride feem ntau yog siv rau hauv cov av nkos ntawm qhov cub tawg loj, thiab ib qho me me yog siv rau hauv cov ntaub ntawv trench lossis lwm yam khoom siv amorphous refractory. Granular ferrosilicon nitride feem ntau yog siv hauv cov nplej-taw qhia silicon steel lossis lwm hom hlau uas siv nitrides los txhim kho lub zog.
Ferrosilicon nitride yog ib hom tshiab ntawm nitride synthesized ntawm qhov kub thiab txias siv cov tshuab nitriding. Nws yog cov khoom ntawm ferrosilicon alloy hmoov rhuab mus rau 1200-1400 degrees Celsius hauv nitrogen thiab nitrided. Nws cov khoom tseem ceeb yog 75% -80 % silicon nitride, thiab tseem muaj cov hlau dawb thiab tsis muaj ferrosilicon. Ferrosilicon nitride muaj cov khoom kub kub zoo, tiv thaiv corrosion, hnav tsis kam thiab sintering zog, siab thermal conductivity, me me thermal expansion coefficient thiab lwm yam zoo. Ntxiv nrog rau kev siv dav hauv cov av nkos hauv qhov cub tawg, nws kuj tseem siv rau hauv cov pa roj carbon refractories. Nws muaj cov ntawv thov dav dav hauv cov ntaub ntawv refractory xws li cov khoom siv hluav taws xob kub thiab cov magnesia castables.
Cov theem muaj pes tsawg leeg ntawm ferrosilicon nitride synthesized los ntawm lub flash combustion txheej txheem yog -Si3N4, -Si3N4, Fe3Si thiab ib tug me me ntawm SiO2. Muaj ntau ntau ntawm columnar silicon nitride crystals nrog qhov sib piv siab hauv cov qauv. Fe3Si yog nyob rau hauv cov ntaub ntawv qhwv los ntawm columnar crystals. Sab hauv, ib qho kev suav nrog yog tsim, nrog cov qauv xoob thiab muaj zog ua haujlwm; ferrosilicon nitride synthesized los ntawm tus kheej-propagating kub kub yog tsim ntawm -Si3N4, -Si3N4, Fe3Si thiab Si2N2O, thiab cov microstructure yog ib tug ntom silicon nitride thaiv. Qhov saum npoo ntawm lub block yog them nrog ib zaj duab xis silicon oxynitride, thiab muaj cov zoo silicon nitride crystals nyob rau hauv qhov sib txawv ntawm cov blocks. Cov hlau-muaj cov khoom siv tau kos rau hauv cov tuab tuab, thiab cov qauv yog ntom thiab cov khoom yog ruaj khov.
