Silicon Nitride cov khoom muaj cov yeeb yam sib txawv:
1.Silicon Nitride muaj cov cuab yeej siab zog. Kev sib tawg lub zog ntawm silicon nitride kub-nias cov khoom yog 500-700Mpa ib txwm ua, txawm tuaj yeem ncav cuag 1000-1200Mpa. Rau cov tshuaj tiv thaiv sintering khoom, feem ntau nws yog 200Mpa, siab dua rau 300-400Mpa.
2. Cov coefficient ntawm liner nthuav ntawm silicon nitride tsawg tsawg uas nquag 2.53X10-6 / ℃ thiab cov thermal conductivity yog 18.42w / m · k. Yog li no, silicon nitride muaj qhov ua tau zoo rau kev ua rau thermal poob siab.
3.Qhov nyuaj ntawm Silicon nitride yog ntau heev. Nws microhardness tus naj npawb yog 3300kg / mm2which tsuas yog tsawg dua li qee qhov ntawm super-zog cov ntaub ntawv zoo li pob zeb diamond. Nws txhuam cov coefficient yog qhov me me thiab nws muaj nws tus kheej-lubricity. Yog li no, silicon nitride yog ib hom khoom siv zoo-hnav nrog kev ua tau zoo rau kev ua kom zoo.
4.Qhov kev cuam tshuam ntawm silicon nitride muaj tsawg cuam tshuam nrog qhov kub thiab txias. Piv txwv li, silicon nitride ntawm cov tshuaj tiv thaiv-sintering txheej txheem ntim 24Mpa hauv qab 1200 ℃ thiab nws cov deformation tsuas yog 0.5% tom qab 1000h.
5.Silicon nitride muaj cov cuab yeej tshuaj lom neeg zoo heev. Nws tuaj yeem tiv thaiv qhov kev yaig ntawm tag nrho cov inorganic acid tshwj tsis yog rau HF acid thiab feem ntau ntawm kua dej alkali. Nws kuj tseem ruaj khov rau feem ntau ntawm cov hlau thiab cov xim hlau yaj, xws li kev yaig ntawm cov hlau tsis zoo, zoo li Zn, Al, Cu, thiab lwm yam. max. nyob rau hauv txo cua
