Khoom Description
Thaum tshav kub kub muaj peev xwm alumina feem ntau yog hais txog lub peev xwm kub ntawm txhuas oxide (Alumina, Al₂O₃). Thaum tshav kub kub muaj peev xwm yog ib qho kev ntsuas ntawm qhov kev hloov ntawm qhov kub thiab txias thaum ib yam khoom absorbs los yog tso cua sov, feem ntau qhia nyob rau hauv units ntawm joules ib kelvin (J / K) los yog joules ib degree Celsius (J / degree ). Rau alumina, nws cov nqi hluav taws xob muaj peev xwm piav qhia qhov kev hloov pauv ntawm qhov kub thiab txias thaum chav tsev loj ntawm alumina absorbs lossis tso tawm chav tsev kub ntawm qhov sib txawv.
Muaj nuj nqi
1. Lub peev xwm ua kom kub tsis tu ncua ntawm alumina muaj qee yam kev sib raug zoo nrog kub. Raws li qhov kub thiab txias, qhov kub tsis tu ncua lub peev xwm ntawm alumina kuj nce raws li. Qhov no yog vim hais tias ntawm qhov kub thiab txias, lub lattice qauv ntawm alumina feem ntau yuav hloov, thiab kev vibrations ntawm molecules yog txhim khu kev qha, uas ua rau muaj kev nce hauv nws lub peev xwm nqus cua sov.
2. Lub peev xwm ua kom kub tsis tu ncua ntawm alumina yog ze rau cov khoom siv purity thiab lattice qauv. Qhov siab dua qhov purity ntawm alumina, qhov ze rau nws qhov siab tas li lub peev xwm kub yog rau tus nqi theoretical. Doped impurities qhia txog qib zog ntxiv thiab kev vibrational hom uas cuam tshuam rau kev ua haujlwm kub ntawm alumina. Alumina nrog cov qauv lattice sib txawv kuj tseem yuav ua rau muaj qhov sib txawv ntawm qhov ntsuas kub tsis tu ncua. Piv txwv li, qhov ntsuas qhov ntsuas kub tsis tu ncua ntawm -Al₂O₃ thiab -Al₂O₃ yog qhov sib txawv.
Daim ntawv thov
1. Cov khoom siv kub thiab cov khoom siv: Vim tias alumina muaj cov cua sov zoo thiab muaj peev xwm ua kom sov, nws ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv kub thiab cov khoom siv. Tsis tas li ntawd, alumina kuj tau siv dav hauv tsheb cav lub tog raj kheej lub taub hau npog, sealing rings nyob rau sab saum toj ntawm piston, valve qhia thiab lwm yam khoom. Cov khoom no ua haujlwm ntawm qhov kub thiab txias, thiab cov khoom zoo ntawm alumina tuaj yeem ua tau raws li lawv cov kev xav tau ua haujlwm.
2. Kev lag luam tshuaj: Lub peev xwm ua haujlwm kub ntawm alumina ua rau nws yog ib qho tseem ceeb hauv kev lag luam tshuaj. Raws li cov cab kuj catalyst, alumina tuaj yeem muab qhov chaw ruaj khov thiab txhawb cov tshuaj tiv thaiv. Nyob rau tib lub sijhawm, alumina kuj tuaj yeem siv los ua cov ntaub thaiv corrosion-resistant rau cov khoom siv tshuaj los tiv thaiv cov khoom siv los ntawm cov khoom siv tshuaj.
3. Kev lag luam hluav taws xob: Alumina kuj tau siv dav hauv kev lag luam hluav taws xob. Vim tias txhuas oxide muaj cov khoom zoo insulating thiab kub ruaj khov, nws feem ntau yog siv los ua cov khoom siv hauv paus thiab insulating txheej rau cov khoom siv hluav taws xob. Aluminium oxide ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hluav taws xob xws li kev sib xyaw ua ke, cov lus qhia, thiab LEDs.
4. Aerospace teb: Lub tshav kub muaj peev xwm ntawm alumina kuj ua rau nws muaj peev xwm siv nyob rau hauv aerospace teb. Txij li cov khoom siv hauv aerospace ua haujlwm nyob rau hauv qhov kub thiab txias ib puag ncig, aluminium oxide zoo heev tiv thaiv tshav kub thiab kub muaj peev xwm ua rau nws yog ib qho khoom siv zoo tshaj plaws.
