Mitundu isanu ndi umodzi ya matenthedwe omwe amagwiritsidwa ntchito kwambiri ma nanomatadium
1. Nano diomand
Daimondi ndi zinthu zomwe zimakhala ndi matenthedwe apamwamba kwambiri m'chilengedwe, zokhala ndi matenthedwe mpaka 2000 W/(mK) kutentha kwa firiji, kuchuluka kwa matenthedwe pafupifupi (0.86±0.1)*10-5/K, ndi kutenthetsa mchipinda. kutentha.Kuonjezera apo, diamondi imakhalanso ndi makina abwino kwambiri, omvera, optical, magetsi ndi mankhwala, zomwe zimapangitsa kuti zikhale ndi ubwino wodziwikiratu pakutayika kwa kutentha kwa zipangizo zamtundu wa photoelectric, zomwe zimasonyezanso kuti diamondi ili ndi mphamvu yogwiritsira ntchito kwambiri m'munda wotentha kutentha.
2. BN
Mapangidwe a kristalo a hexahedral boron nitride ndi ofanana ndi mawonekedwe a graphite wosanjikiza.Ndi ufa woyera womwe umadziwika ndi lotayirira, mafuta, kuyamwa kosavuta ndi kulemera kwake. argon pa kutentha mpaka 2800 ℃. Sikuti ali ndi mphamvu yowonjezera yowonjezera kutentha, komanso imakhala ndi matenthedwe apamwamba, sikuti ndi woyendetsa bwino wa kutentha, koma ndi insulator yamagetsi. ku 300k.
3. SIC
Katundu wa silicon carbide ndi wokhazikika, ndipo kutentha kwake kumakhala bwino kuposa zodzaza semiconductor zina, ndipo kutentha kwake kumakhala kokulirapo kuposa chitsulo kutentha kwachipinda. Zotsatira zake zikuwonetsa kuti kutenthetsa kwa mphira wa silikoni kumawonjezeka ndi kuwonjezeka kwa kuchuluka kwa silicon carbide. .
4. ALN
Aluminiyamu nitride ndi kristalo wa atomiki ndipo imatha kukhalapo mokhazikika pa kutentha kwakukulu kwa 2200 ℃.Pokhala ndi ma conductivity abwino a matenthedwe ndi kagawo kakang'ono ka kuwonjezereka kwa kutentha, ndi chinthu chabwino chopanda kutentha. silicon carbide ndi nthawi zopitilira 5 kuposa alumina.
Njira yogwiritsira ntchito: silika gel osakaniza dongosolo, matenthedwe pulasitiki dongosolo, matenthedwe epoxy utomoni dongosolo, matenthedwe ceramic mankhwala.
5. AL2O3
Alumina ndi mtundu wa multifunctional inorganic filler, wokhala ndi matenthedwe akulu, dielectric mosalekeza komanso kukana kuvala bwino, amagwiritsidwa ntchito kwambiri muzinthu zophatikizika za mphira, monga silika gel, potting sealant, epoxy resin, pulasitiki, mphira matenthedwe madutsidwe, matenthedwe matenthedwe pulasitiki. , mafuta a silicone, zitsulo zotayira kutentha ndi zipangizo zina.Pogwiritsa ntchito, Al2O3 filler ingagwiritsidwe ntchito yokha kapena kusakaniza ndi zodzaza zina monga AIN, BN, etc.
6.Carbon Nanotubes
The matenthedwe madutsidwe wa carbon nanotubes ndi 3000 W · (m·K) -1, 5 nthawi zamkuwa. Mpweya nanotubes akhoza kwambiri kusintha matenthedwe matenthedwe madutsidwe, madutsidwe ndi katundu thupi la mphira, ndi kulimbikitsa ndi matenthedwe madutsidwe wabwino kuposa chikhalidwe zodzaza monga kaboni wakuda, kaboni fiber ndi galasi fiber.
