High thermal conductivity thiab qis coefficient ntawm thermal expansion. Qhov kev sib xyaw ua ke ntawm cov khoom no muab qhov tshwj xeeb thermal shock tsis kam, ua rau Silicon Carbide ceramics pab tau ntau yam kev lag luam. Nws kuj yog ib qho semiconductor thiab nws cov khoom hluav taws xob ua rau nws haum rau ntau yam kev siv. Nws kuj tseem paub txog nws qhov hnyav hardness thiab corrosion kuj.

Aluminium nitride muaj cov thermal conductivity siab (170 W / mk, 200 W / mk, thiab 230 W / mk) nrog rau cov ntim siab thiab lub zog dielectric.

Thermal shock feem ntau yog thawj qhov ua rau tsis ua haujlwm hauv cov ntawv thov kub. Nws yog tsim los ntawm peb yam: thermal expansion, thermal conductivity, thiab lub zog. Kev hloov pauv kub ceev, ob qho tib si nce thiab nqis, ua rau qhov sib txawv ntawm qhov kub thiab txias, zoo ib yam li qhov tawg uas tshwm sim los ntawm rub lub khob dej khov rau lub khob kub. Vim qhov sib txawv expansion thiab contraction, txav

Kev lag luam automotive yog ua raws li kev tsim kho tshiab los ntawm kev siv cov txheej txheem thev naus laus zis los tsim cov kev hloov pauv hloov hauv nws cov txheej txheem tsim khoom thiab cov khoom tshwj xeeb ntawm cov tsheb tshiab.

Bearings thiab li qub yog ob qhov kev siv ntau tshaj plaws rau silicon nitride ceramic pob. Kev tsim cov pob silicon nitride siv cov txheej txheem uas ua ke nrog isostatic nias nrog roj siab sintering. Cov khoom siv raw rau cov txheej txheem no yog silicon nitride hmoov zoo nrog rau cov khoom siv sintering xws li txhuas oxide thiab yttrium oxide.

Muaj ntau yam khoom siv niaj hnub no, suav nrog alumina, zirconia, beryllia, silicon nitride, boron nitride, aluminium nitride, silicon carbide, boron carbide, thiab ntau ntxiv. Txhua yam ntawm cov ceramics siab heev muaj nws tus kheej tshwj xeeb ntawm kev ua tau zoo thiab qhov zoo. Txhawm rau ua kom tau raws li cov kev cov nyom uas tau nthuav tawm los ntawm cov ntawv thov hloov mus tas li, cov ntaub ntawv tshiab yog sib xws

Zirconia muaj zog heev vim nws qhov tshwj xeeb tetragonal siv lead ua qauv, uas feem ntau yog tov nrog Yttria. Zirconia cov nplej me me ua rau cov neeg tsim khoom tuaj yeem ua cov ntsiab lus me me thiab cov npoo ntse uas tuaj yeem sawv ntsug rau kev siv ntxhib.

Tsawg tus neeg paub txog ntau npaum li cas kev lag luam siv cov txheej txheem ceramics hauv ib hnub. Technical ceramics yog cov khoom siv ntau yam uas tuaj yeem siv tau hauv ntau qhov kev lag luam rau ntau lub hom phiaj ntxim nyiam. Technical ceramics tau tsim los rau ntau yam kev siv.

Rau kev ntim khoom siv hluav taws xob, ceramic substrates ua lub luag haujlwm tseem ceeb hauv kev sib txuas cov kab hluav taws xob sab hauv thiab sab nraud, nrog rau kev sib txuas hluav taws xob thiab kev txhawb nqa txhua yam. Ceramic substrates muaj qhov zoo ntawm cov thermal conductivity, zoo tshav kub tsis kam, siab mechanical zog, thiab tsawg coefficient ntawm thermal expansion, thiab lawv yog cov khoom siv substrate.

Lub hauv paus ntsiab lus ntawm kev tiv thaiv armor yog siv lub zog ntawm qhov projectile, qeeb nws thiab ua rau nws tsis muaj mob. Thaum feem ntau cov khoom siv hluav taws xob, xws li hlau, nqus lub zog los ntawm cov txheej txheem deformation, thaum cov ntaub ntawv ceramic nqus zog los ntawm cov txheej txheem micro-fragmentation.
