Silicon nitride xyaw nrog silicon carbide hnav-resistant cov ntaub ntawv yog cov neeg siv roj nitrogen-carbon bonded silicon carbide khoom, nws tus cwj pwm yog tshwm sim hauv ntau yam, ua ntej txhua yam, zoo thermal poob siab thiab siab kub creep kuj. Yog hais tias qhov loj me me thaum lub sij hawm kub thiab txias txias, thaum lub ntsuas kub txias li ntawm 1300 ° C mus rau 20 ° C, nws yuav siv sij hawm ntau pua cua kub cua, tab sis qhov no yuav tsis ua rau cov khoom siv thiab ua kom tsawg lub sij hawm tua hluav taws.
Tsis tas li ntawd, nyob rau hauv kev tsim cov txheej txheem ntawm cov roj nitrogen-carbon bonded silicon carbide khoom, qhov hloov ntawm qhov ntev yog tsawg dua 1%, thiab vim yog tsis muaj iav theem, cov khoom tsis tshuam deev hauv cov huab cua kub nyhiab, thiab yog li cov khoom pov tseg thiab cov khoom yog deformed. Qhov teeb meem no yuav tsis tshwm sim.
Cov tshuaj oxidation tsis zoo, kev txhav thiab ua haujlwm tsis muaj zog kuj tseem ceeb heev ntawm nitrogen-carbon bonded silicon carbide cov khoom, uas tuaj yeem feem ntau ntawm alkali corrosion thiab inorganic acid corrosion; tuaj yeem tiv thaiv cov hlau txhuas thiab txhuas txhuas txhuam thiab txhuam ntawm cov hlau tsis zoo, qhov rai zoo ntawm cov ntsiab lus kub kub.
Tsis tas li ntawd, nitrogen-carbon bonded silicon carbide cov khoom muaj zog ua tau yooj yim, thiab lawv cov chav nyob hauv qhov kub thiab txias qhov ob lub zog yog ob zaug ntawm cov av nplaum silicon carbide khoom. Yog hais tias cov txheej txheem amorphous tsis muaj nyob hauv, chav tsev kub yog khaws cia hauv qhov ntau ntawm 1200 ° C mus rau 1400 ° C, thiab lub zog ntawm cov khoom siv tiv taus hnyav dua ntxiv rau 9 npaug ntawm cov av nplaum silicon carbide product.http: / /www.hshightec.com/
