Khoom Description
Silicon nitride (Si3N4) yog ib qho tseem ceeb ntawm cov khoom siv ceramic. Nws yog grey, dawb los yog tawm-dawb hmoov. Qhov ntom ntawm silicon nitride ceramics yog qhov tsawg, tsuas yog 41% ntawm cov kabmob steel, tab sis tus nqi tshwj xeeb txawv nyob ntawm txoj kev npaj thiab cov xwm txheej. Piv txwv li, qhov ceev ntawm Si3N4 ua los ntawm cov tshuaj tiv thaiv sintering yog 1.8 ~ 2.7g / cm3, thiab qhov ceev ntawm Si3N4 ua los ntawm kub nias yog 3.12 ~ 3.22g / cm3. Lub hardness ntawm silicon nitride yog siab heev, thib ob tsuas yog pob zeb diamond thiab cubic boron nitride, nrog ib tug Mohs hardness ntawm 9 ~ 9.5, Vickers hardness txog 2200, thiab ib tug microhardness txog li 32630MPa. Silicon nitride tsis muaj melting point thiab feem ntau decomposes nyob ib ncig ntawm 1900 degree nyob rau hauv ib txwm siab. Lub melting point yuav ncav cuag 1900 degree nyob rau hauv siab. Silicon nitride muaj tshuaj lom neeg ruaj khov. Tsuas yog hydrofluoric acid, nws tsis hnov mob nrog lwm cov inorganic acids. Nyob rau tib lub sijhawm, nws tuaj yeem tiv thaiv corrosion los ntawm ntau yam organic acids thiab caustic soda daws hauv qab 30%.
Txoj kev npaj ntawm silicon nitride feem ntau suav nrog kev ncaj qha nitridation ntawm silicon hmoov, carbon thermal txo, thermal decomposition, sol-gel, tshuaj vapor deposition thiab nws tus kheej-propagating txoj kev, thiab lwm yam. purity thiab kev ua tau zoo ntawm silicon nitride tau kuj txawv.
Silicon nitride yog dav siv nyob rau hauv ntau lub teb thiab kev lag luam vim nws cov khoom zoo heev xws li siab zog, siab hardness, zoo hnav tsis kam, kub tsis kam, thermal shock kuj thiab zoo tshuaj stability. Piv txwv li, nyob rau hauv lub machinery manufacturing kev lag luam, silicon nitride yuav siv tau raws li cov cuab yeej txiav, hnav-resistant qhov chaw xws li bearings, npas, mechanical seals, thiab lwm yam., tshwj xeeb tshaj yog, silicon nitride ceramic bearings muaj siab precision, siab ceev, siab load thiab kev ua haujlwm zoo hauv qhov kub thiab txias. Hauv thaj chaw aerospace, silicon nitride tuaj yeem siv rau lub cav qhov chaw, turbine hniav thiab lwm qhov chaw ua haujlwm nyob rau hauv qhov kub thiab txias. Nws qhov kub thiab txias tsis kam tuaj yeem ua kom ntseeg tau tias cov khoom no muaj kev ruaj ntseg hauv qhov kub thiab txias. Hauv kev lag luam automotive, silicon nitride tuaj yeem siv rau hauv lub cav qhov chaw xws li turbocharger rotors, bearings thiab li qub, uas yuav pab txhim kho lub cav efficiency thiab kav ntev.
Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis thiab kev ua kom nrawm ntawm kev lag luam, daim ntawv thov teb ntawm silicon nitride yuav txuas ntxiv. Nyob rau tib lub sijhawm, kev npaj thev naus laus zis ntawm silicon nitride yuav txuas ntxiv txhim kho thiab tsim kho tshiab los txhim kho nws cov purity thiab kev ua tau zoo kom tau raws li cov kev xav tau ntawm qib siab dua. Tshwj xeeb tshaj yog nyob rau hauv lub tshav pob ntawm cov ntaub ntawv tshiab, silicon nitride yuav ua lub luag hauj lwm tseem ceeb thiab txhawb txoj kev loj hlob thiab kev vam meej ntawm cov lag luam muaj feem xyuam.
