Izinhlobo eziyisithupha zama-nanomatadium ezisetshenziswa kakhulu ezishisayo

1. Nano diomand

Idayimane liyinto enokushintshwa okushisayo okuphezulu kakhulu kwendalo, ene-thermal conductivity efinyelela ku-2000 W/(mK) ekamelweni lokushisa, i-thermal coefficient yokwandisa cishe (0.86±0.1)*10-5/K, kanye ne-insulation ekamelweni izinga lokushisa.Ngaphezu kwalokho, idayimane libuye libe nezinto ezinhle kakhulu zemishini, i-acoustic, optical, kagesi kanye namakhemikhali, okwenza kube nezinzuzo ezisobala ekuqothulweni kokushisa kwemishini ye-photoelectric enamandla amakhulu, okubonisa futhi ukuthi idayimane inamandla amakhulu okufaka isicelo endaweni yokushisa ukushisa.
2. BN

Isakhiwo sekristalu se-hexahedral boron nitride sifana nesakhiwo se-graphite layer.Impushana emhlophe ebonakala ngokuxega, ukuthambisa, ukumuncwa kalula kanye nesisindo esincane.Ukuminyana kwethiyori ku-2.29g/cm3, ubulukhuni be-mohs bungu-2, futhi izakhiwo zamakhemikhali zizinzile ngokwedlulele.Umkhiqizo unokumelana nomswakama ophezulu futhi ungasetshenziswa ku-nitrogen noma i-argon emazingeni okushisa afinyelela ku-2800℃.Ayinayo nje kuphela i-coefficient yokwandisa ukushisa okuphansi, kodwa futhi ine-conductivity ephezulu yokushisa, ayiyona nje i-conductor enhle yokushisa, kodwa i-insulator kagesi evamile.I-conductivity yokushisa ye-BN yayingu-730w / mk ngo 300k.

3. I-SIC

Impahla yamakhemikhali ye-silicon carbide izinzile, futhi ukuqhutshwa kwayo okushisayo kungcono kunezinye izithasiselo ze-semiconductor, futhi ukuqhutshwa kwayo kwe-thermal kukhulu nakakhulu kunensimbi ekamelweni lokushisa. Irabha ye-silicone eqinisiwe. Imiphumela ibonisa ukuthi ukushiswa kwerabha ye-silicone kuyanda ngokukhula kwenani le-silicon carbide. Ngenani elifanayo le-silicon carbide, ukuqhutshwa kokushisa kwerabha ye-silicon eqiniswe ngosayizi wezinhlayiyana ezincane kukhulu kunosayizi wezinhlayiyana ezinkulu. .

4. ALN

I-Aluminium nitride iyikristalu ye-athomu futhi ingaba khona ngokuzinzile ezingeni lokushisa eliphezulu elingu-2200 ℃.Ngokusebenza kahle kwe-thermal kanye ne-coefficient encane yokunwetshwa kokushisa, iyinto enhle enomthelela ekushiseni.I-thermal conductivity ye-aluminium nitride ingu-320 W· (m·K) -1, eseduze ne-thermal conductivity ye-boron oxide futhi i-silicon carbide kanye nezikhathi ezingaphezu kwezi-5 kune-alumina.
Isiqondiso sokufaka isicelo: i-thermal silica gel system, i-thermal plastic system, i-thermal epoxy resin system, imikhiqizo ye-ceramic eshisayo.

5. I-AL2O3

I-Alumina iwuhlobo lwe-multi-functional inorganic filler, ene-thermal conductivity enkulu, i-dielectric engaguquki futhi ukumelana nokugqokwa okungcono, esetshenziswa kabanzi ezintweni eziyinhlanganisela yenjoloba, njenge-silica gel, i-potting sealant, i-epoxy resin, ipulasitiki, i-rubber conductivity eshisayo, ipulasitiki ye-thermal conductivity. , i-silicone grease, i-ceramics yokulahla ukushisa nezinye izinto.Ekusetshenzisweni okusebenzayo, isigcwalisi se-Al2O3 singasetshenziswa sodwa noma sixutshwe nezinye izihlungi ezifana ne-AIN, BN, njll.

6.I-Carbon Nanotubes

I-thermal conductivity ye-carbon nanotubes yi-3000 W· (m·K) -1, izikhathi ezingu-5 kunethusi.I-carbon nanotubes ingathuthukisa kakhulu ukuqhutshwa kwe-thermal, conductivity kanye nezakhiwo zomzimba zenjoloba, futhi ukuqiniswa kwayo nokushisa kwe-thermal kungcono kunendabuko. ama-fillers afana ne-carbon black, i-carbon fiber kanye ne-glass fiber.
