Hom ntawm Silicon Nitride

Reaction Bonded silicon nitride (RBSN):Kev kho mob ntawm RBSN thawj zaug ua silicon "dough" lossis pob, thiab tom qab ntawd dhau los ua cov txheej txheem tawv tawv hu ua nitriding ntawm qhov kub txog li 1450 degree. Piv nrog rau lwm hom silicon nitride, RBSN yog qhov ntxeem tau ntau dua (porosity yog li 25%) thiab tsis zoo li lwm hom silicon nitride hauv cov khoom siv kho tshuab.

Kub- nias silicon nitride (HPSN):Nws yog tsim los ntawm kev sib xyaw ntawm cov hmoov zoo Si3N4 hmoov thiab magnesia flux hauv graphite pwm thiab raug kub thiab siab siab (feem ntau 1800℃thiab 40MPa). Piv nrog RBSN, nws muaj qhov ceev dua thiab cov khoom siv kho tshuab zoo dua.

Sintered cov tshuaj tiv thaiv bonded silicon nitride (SRBSN):SRBSN yog qhov hloov tshiab ntawm RBSN. Txhawm rau txo qhov porosity ntawm cov khoom kawg, sintering additives yog ntxiv rau thawj cov hmoov sib tov thiab tom qab ntawd pab kom nws yuav tsum tau sintered tom qab cov tshuaj tiv thaiv kab mob theem (ntawm qhov kub siab tshaj 1800℃thiab atmospheric siab).

Sintered silicon nitride (SSN):Txhawm rau tsim SSN, silicon nitride tsis muaj zog sintered ntawm li 1750 degree, ua ke nrog sintering additives xws li magnesia, yttrium oxide thiab alumina los txhawb cov txheej txheem densification. Qhov ceev yog 98%, thiab qhov siv ntau yog 600-700 MPa.

Nta ntawm Silicon Nitride

Silicon nitride yog ruaj khov nyob rau hauv muaj nitric, sulfuric thiab hydrochloric acids, thiab reacts tsis zoo nrog orthophosphoric acid. Txawm li cas los xij, nws muaj zog ntau dua nrog hydrofluoric acid. Silicon nitride yog decomposed los ntawm alkali melts, oxides thiab carbonates ntawm alkali hlau. Nws tsis hnov mob nrog chlorine txog 900 degree, hydrogen sulfide mus txog 1000℃thiab hydrogen txog 1200 degree. Nws tsis cuam tshuam nrog Al, Pb, Sn, Zn, Bi, Cd, Cu melts; Txawm li cas los xij, nws tsim silicides nrog kev hloov pauv hlau thiab silicates nrog hlau oxides ntawm qhov kub siab tshaj 1200 degree. Oxidation ntawm silicon nitride hauv huab cua pib ntawm qhov kub siab tshaj 900 degree.

Kev siv Silicon Nitride Scenarios

Daim ntawv thov nyob rau hauv ironmaking refractories:Nws muaj kev tiv thaiv corrosion zoo, kev tiv thaiv corrosion thiab yaig tsis kam, thiab kev pab cuam lub neej ntawm torpedo hauv ob sab phlu refractory khoom yog zoo heev.

Kev tsim khoom ntawm Silicon Nitride

Silicon nitride yog ib qho nyuaj rau tsim raws li cov khoom siv ntau-nws tsis tuaj yeem ua kom sov tshaj 1850 degree, uas yog qis dua nws qhov melting point, vim dissociation rau silicon thiab nitrogen. Yog li ntawd, kev siv cov pa kub xovxwm sintering cov tswv yim yog teeb meem. Bonding ntawm silicon nitride hmoov tuaj yeem ua tiav ntawm qhov kub thiab txias los ntawm kev ntxiv cov khoom hu ua sintering aids lossis "binders", uas feem ntau ua rau muaj qib ntawm cov kua theem sintering. Ib qho kev ntxuav huv yog siv cov pa roj plasma sintering, qhov chaw cua sov ua haujlwm sai heev (thib ob) los ntawm kev hla cov pulses ntawm hluav taws xob tam sim no los ntawm cov hmoov compacted. Qhov ntom ntom silicon nitride compacts tau txais los ntawm cov txheej txheem no ntawm qhov kub ntawm 1500-1700 degree.
