Siab Melting Point
Ib qho ntawm cov khoom siv thermal tseem ceeb ntawm alumina ceramic yog nws qhov siab melting point. Nrog rau qhov kub thiab txias tshaj 2000 degrees Celsius, alumina ceramic tuaj yeem tiv taus huab cua kub, ua rau nws tsim nyog rau kev siv xws li cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab cov khoom siv hluav taws xob.
Tsawg Thermal Expansion Coefficient
Alumina ceramic kuj boasts ib coefficient tsawg ntawm thermal expansion. Cov cuab yeej no txhais tau hais tias cov khoom muaj kev hloov pauv me me raws li qhov kub thiab txias. Vim nws tsis tshua muaj thermal expansion, alumina ceramic yog zoo meej rau kev siv uas mus los ntawm ntau yam kub hloov. Qhov no yog vim qhov tseeb tias nws txo qis qhov tshwm sim ntawm kev tawg lossis tawg vim kev ntxhov siab los ntawm kev hloov pauv kub.
Zoo heev thermal conductivity
Tsis tas li ntawd, alumina ceramic muaj cov thermal conductivity zoo heev. Nws lub peev xwm los ua kom muaj cua sov ua kom muaj txiaj ntsig zoo hauv kev siv lub dab dej kub, cov khoom siv hluav taws xob, thiab cov txheej txheem thermal barrier coatings. Lub siab thermal conductivity ntawm alumina ceramic tso cai rau cov cua sov kom zoo, tiv thaiv kev tsim cov cua sov ntau hauv cov khoom siv hluav taws xob thiab cov tshuab.
Siab Thermal Shock Resistance
Ntxiv nrog rau nws cov thermal conductivity zoo, alumina ceramic kuj tuaj yeem ua rau lub siab thermal poob siab. Thermal shock tshwm sim thaum cov khoom hloov pauv kub sai, ua rau muaj kev ntxhov siab thiab tsis ua haujlwm. Alumina ceramic tsis kam rau thermal shock yog tshwj xeeb tshaj yog muaj txiaj ntsig hauv cov ntawv thov cuam tshuam nrog qhov kub thiab txias hloov pauv, xws li hauv kev lag luam aerospace thiab automotive industries.
Hauv kev xaus, alumina ceramic lub thermal zog, nrog rau nws qhov siab melting point, tsis tshua muaj thermal expansion, thermal conductivity zoo heev, thiab thermal shock kuj, pab txhawb rau nws txoj kev siv dav hauv ntau hom kev lag luam. Txawm hais tias nyob rau hauv huab cua kub ib puag ncig lossis kev siv uas xav tau kev tswj xyuas kom zoo, alumina ceramic sawv tawm raws li cov khoom siv ruaj khov thiab ruaj khov nrog kev ua haujlwm zoo thermal.
