Ceramics muaj daim ntawv thov loj loj hauv kev tshaj tawm hauv cov kev lag luam tawm tswv yim xws li ib lub zog, lub zog hluav taws xob tshiab, thiab cov cuab yeej siv siab.
Raws li cov ntaub ntawv tshiab ntawm Tuam Tshoj Tuam Tshoj ntawm cov chaw tsim khoom lag luam hauv tsheb, txij lub Ib Hlis Ntuj mus rau lub Kaum Ib Hlis, kuv lub tebchaws tau ua tiav rau cov muaj kwv yees li ntawm 100%, nrog a Kev sib qhia ua lag luam 25%. Ntxiv nrog rau kev loj hlob ntawm kev tsim khoom thiab muag khoom deb tshaj li kev ua lag luam nyob rau tib lub sijhawm, kev nkag mus rau lub zog hluav taws xob tshiab kuj tau tshaj li 36% thiab tseem nce ntxiv. Nrog kev nce qib nruam ntawm cov tsheb hluav taws xob thev naus laus zis, hloov cov ntaub ntawv tiv thaiv thiab cov qauv tsim yog nrawm. Cov ntaub ntawv tshaj lij ceramic tau raug pom zoo rau hauv daim ntawv thov hluav taws xob hluav taws xob tshiab nrog lawv cov kev ua tau tshwj xeeb. Ntawm lawv, lub duav silicon nitride coj cov pob thiab siab thermal conductivity silicon nitride subtrates yog nrov heev.
Nrog rau kev txhim kho ntawm tib neeg lub neej thiab kev txhim kho cov neeg kho mob ntawm cov tshuab ua pa thiab cov khoom siv dag ntxias yuav dhau los thiab ntau dua. Cov ntaub ntawv hlau xws li cov ntaub pua hlau thiab cobalt alloys tau ntev tau siv ua orthopedics nyob rau hauv kuv lub teb chaws vim yog lawv cov khoom siv zoo dua thiab tswj cov khoom. Yog li ntawd, kev tshawb fawb thiab kev ua lag luam rau bioceramics lossis txheej cov ntaub ntawv nrog zoo sib xyaw thiab kev noj qab haus huv tau tawg.
Biomedical ceramics xws li Al2o3, ZURO2, SI3N4 thiab lawv cov cerams cov ntaub ntawv, kev hloov pob txha, pob txha, pob txha, pob txha ua kom zoo nkauj thiab hnav tsis kam. Ntawm lawv, silicon nitride cov nyhuv muaj txiaj ntsig thiab lubrice-lubricating cov khoom yog sib xyaw ua ke, thiab ruaj khov raws li kev ruaj khov thaum siv ua kev cog lus; Feem ntau cov ntaub ntawv kho hniav feem ntau siv los ua cov ntaub ntawv rov qab kho dua vim nws qhov kev ua tau zoo thiab kev pom zoo, tab sis nws lub zog yog vim tias vim iav ceramics.
Lub ntiaj teb kev kho mob cov ntaub ntawv lag luam muaj feem ua lag luam muaj feem ntau ntawm Asmeskas $ 15 nphom hauv 2022. Hauv Suav, kev lag luam muaj cov ntaub ntawv kho mob muaj txiaj ntsig hauv 2022 yuav yog kwv yees li ntawm Asmeskas $ 4.5 txhiab nyiaj. Ntawm lawv, Alumina Ceramics account rau cov feem ntau tshaj plaws, txog 60%. Yuav siv cov kab ke ntawm daim teb hniav dawb huv si hauv daim teb hniav, thaum Silicon Nitride Ceramics yog siv rau hauv orthopedic kev cog lus.
Hauv ntau daim ntawv thov ib puag ncig, ceramics ib txwm sawv nrog lawv ua tau zoo heev. Ntawm lawv, Aerospace thiab cov tub rog lag luam yog cov kev lag luam nrov heev rau cov ceramics. Hauv kev lag luam hauv lub lag luam Aerospace, "kev kub siab sai" thiab "stealth" yog ob kab kev txhim kho ntawm ceramics. Raws li lub peev xwm ntawm ib lub muaju, thermal teeb meem txheej txheem thiab cov cua txias ua rau lub zog tshiab ntawm cov tub rog ntawm tub rog tau dhau los ua kev nce qib tshiab, thiab SIC / SIC / SIC / SIC / SIC / SIC / SIC-CMC tau dhau los ua ib qho ntawm thawj qhov kev xaiv rau cov khoom siv kub-resistant cov ntaub ntawv. Silicon carbide fiber plays ua kev txhawb zog thiab ua kom nruj rau hauv Sic / Sic-CMC. Silicon carbide fiber ntau nrog kub tsis kam ntawm ntau dua 1200 degree yog cov khoom tseem ceeb tshaj plaws rau Sic / Sic-CMC thiab tau dhau los ua kev tshawb fawb thiab kev sib tw ntawm lub hwj chim aviation.
Cov khoom nqus yog ib qho ntawm cov khoom siv stealth tseem ceeb tshaj plaws. Nws yog feem ntau muaj ntawm cov khoom sib dhos (lossis phau ntawv binder) thiab ib qho nruab nrab nruab nrab (nqus). Ntawm cov khoom siv sib xyaw cov khoom siv sib xyaw ua ke, silicon carbide yog lub ntsiab tivthaiv rau kev ua ntau pawg absawbing cov ntaub ntawv; Tej hub infrared stealth cov khoom yog ib txheej ntawm inorganic conteramic nanomaterials thiab inorger cov ntaub ntawv. Los ntawm finely tswj inorganic ceramic ceramic ceramic ceramasety dispersed nyob rau hauv inorganic polymer matrix kom ua tiav qhov broadband hluav taws xob hluav taws xob compression.
