Kev ruaj khov ntawm ferrosilicon nitride

Ferrosilicon nitride yog sib xyaw nrog SI3N4 raws li lub ntsiab tivthaiv, feem ntau nrog cov hlau dawb, thiab ib qho me me ntawm lwm yam. Nws yog dav siv nyob rau hauv statmaking thiab refractory cov khoom tsim, tshwj xeeb tshaj yog cov sib zog ua kom sov. Nws tuaj yeem txhim kho cov khoom siv ntawm cov kua dej drilling thiab ua kom tau raws li qhov xav tau ntawm cov cua sov ua kom sov. Qhov kev ruaj ntseg ntawm ferrosilicon nitride qhia tau zoo thaum muaj kev kub siab, tshwj xeeb hauv cov huab cua nitrogen, qhov twg nws tuaj yeem tswj qhov kev ruaj khov.



Kev tshawb fawb txog qhov kev kub ntxhov siab ntawm ferrosilicon nitride nyob rau hauv ib puag ncig nitrogen pom tau tias theem muaj kev hloov pauv nrog qhov nce ntawm qhov ntsuas kub. Piv txwv li, ntawm qhov kub ntawm 1500 degree, ntsuas xws li -si3n4, -si3n4, si2n2o, Sic thiab Fes3Si yog tam sim no hauv tus qauv; Thaum 1600 degree, cov -SI3N4 cov ntsiab lus nce, thiab peb ferrosilicon alloys - FE3Si, FESII3 thiab FESI - CEASTI. Nyob rau tib lub sijhawm, -si3N4 thiab si2n2o ploj; Thaum qhov kub nce mus rau 1700 degree, as -si3N4 cov ntsiab lus txo qis, theiSi3N4, Fesi theem kauj, thiab FE3Si theem ploj.



Qhov kev ruaj ntseg ntawm ferrosilicon nitride kuj muaj feem xyuam rau nws qhov loj me. Qhov loj dua me me ntawm ferrosilicon hmoov ferrosilicon hmoov ferrosilide tshuaj lom zem heev vim tias cov tshuaj tiv thaiv nitride ntau dhau ntawm cov tshuaj tiv thaiv, yog li zam dhau overbaking. Tsis tas li ntawd, ferrosilicon nitride muaj ntau qhov zoo, xws li muaj hluav taws kub ua rau, muaj zog kho tshuab, thiab cov oxidation tsis kam.
