Beta Silicon Nitride -Si3N4 Nqe lus piav qhia
-Si3N4 (Beta Phase) yog lwm hom qauv ntawm silicon nitride (Si3N4) paub txog nws cov khoom tshwj xeeb thiab dav - ntau yam kev siv:
- Cubic Symmetry:-Si3N4 muaj lub cubic siv lead ua qauv, paub txog nws qhov sib npaug ntawm qhov cubic unit cell kev npaj.
- Siab -Tsub stability:Hauv kev sib piv rau -Si3N4, -Si3N4 nthuav tawm qhov zoo tshaj plaws thermal stability ntawm qhov kub siab dua, feem ntau txog li ntawm 1900℃.
- Mechanical Robustness:Nws boasts superior mechanical zog, ua rau nws zoo tagnrho rau daim ntaub ntawv uas xav tau lub zog, toughness, thiab kuj mus rau huab cua.
- Daim ntawv thov:-Si3N4 yog siv nyob rau hauv ib puag ncig kub rau aerospace qhov chaw, cov cuab yeej txiav, thiab cov kabmob uas ua rau muaj zog txhua yam thiab thermal zog.
Ob theem tseem ceeb ntawm Si3N4 muaj cov txiaj ntsig sib txawv thiab qhov tsis zoo. Qhov no pab cov engineers thiab cov kws tshawb fawb xaiv cov theem zoo rau lawv cov kev xav tau.

Kev ua haujlwm
Silicon nitride cov khoom yog tsim los ntawm sintering ntawm qhov kub thiab txias, kub nias, thiab pyrolysis ntawm silicon tebchaw. High- cov khoom lag luam zoo yog tsim los ntawm sintering hauv cov pa roj- static units nyob rau hauv siab siab nyob rau hauv muaj nitrogen.
Silicon nitride nyuaj kom tau raws li ib qho khoom siv vim tias nws tsis tuaj yeem ua kom sov siab tshaj 1850℃- zoo hauv qab lub melting point (silicon thiab nitrogen dissociate). Yog li, kev siv cov pa thermal sintering (kub xovxwm sintering) yog teeb meem. Bonding ntawm silicon nitride hmoov tuaj yeem ua tiav ntawm qhov kub thiab txias los ntawm kev ntxiv cov ntaub ntawv ntxiv, uas feem ntau txhim kho qib sintering. Lwm txoj hauv kev yog lub txim hluav taws xob plasma sintering, qhov twg cov cua sov ua haujlwm sai heev (hauv vib nas this); qhov twg pulses ntawm hluav taws xob tam sim no dhau los ntawm pre- cov hmoov pressed. Cov khoom siv ntom ntom silicon nitride tau txais los ntawm txoj kev no ntawm qhov kub ntawm 1500-1700 degree.
