Cas 24304-00-5 Nano Aluminium Nitride AlN phofo
Likarolo tsa phofo ea AlN:
AlN phofo e na le bohloeki bo phahameng, kabo ea boholo ba likaroloana tse nyane, sebaka se seholo se ikhethileng, sekhahla se tlase sa bongata le lisebelisoa tse betere tsa ho bopa ente.2. Aluminium nitride nano powder e sebelisoa ka motsoako, 'me e na le papali e ntle le silicon ea semiconductor le sebopeho sa eona se setle sa sebopeho se ntlafatsang thepa ea mochine le mocheso oa mocheso oa thepa e kopantsoeng.
Tlhaloso ea phofo ea AlN:
| Ntho | Bohloeki | APS | Mmala | Boima ba Bongata | Foromo ea Crystallographic | boemo ba oksijene | Mokhoa oa ho etsa | SSA |
| XL-AlN phofo | 99% | 50nm | Hlooho | 0.05g/cm3 | Sebopeho sa hexagonal | 0.8% | Plasma CVD | 105m2/g |
Lisebelisoa tsa phofo ea AlN:
AlN phofo e sebelisetsoang ho ntlafatsa ts'ebetso ea epoxy resin Ka Aluminium nitride nanopowder le epoxy resin system, ha litaba tsa Aluminium nitride nanoparticle li fihla ho 1% ~ 5%, mocheso oa mocheso oa khalase o eketseha le module ea elasticity e fihla ho boleng bo phahameng.Ho kenyelletsa Aluminium nitride nanopowder ho lisebelisoa tsa motsoako oa epoxy resin ho fapane ka ho feletseng le ho kenyelletsa Aluminium nitirde micro grain ka sebopeho.AlN phofo hangata e eketsoa e le mofuta oa ntho e matlafatsang mme e ajoa haholo lipakeng tsa liketane tsa thepa ea polymer.Bakeng sa tšebelisano e sa lekaneng holim'a metsi le sebaka se seholo se khethehileng, phofo ea AlN e bontša mosebetsi o matla haholo.Ho sa le joalo, karolo ea thollo ea Aluminium nitride nanoparticles e ajoa sebakeng sa ketane ea polymer.Ha ho bapisoa le Aluminium nitride micro grain, AlN powder e na le mokelikeli o motle haholo 'me e ka ntlafatsa haholo matla, botsitso le tractility ea epoxy resin.
AlN phofo e sebelisetsoang mocheso o tsamaisang mocheso
Gel ea silica e kopantsoeng le phofo ea AlN, e nang le conductivity e phahameng ea mocheso, e fana ka conductivity e ntle haholo ea mocheso, ho kenya motlakase, mocheso o pharaletseng oa mocheso oa motlakase (-60 ℃ ~ -200 ℃), botenya bo tlase le ts'ebetso e ntle ea ts'ebetso, 'me e ka ba teng ka bophara. e sebelisoang mocheng oa phetisetso ea mocheso oa karolo ea elektroniki ho ntlafatsa ts'ebetso ea ts'ebetso, joalo ka mochini oa radiator oa CPU, audion ea matla a phahameng, likarolo tsa Silicon tse laolehang, diode, mochini oa phetisetso ea mocheso ka har'a seam joalo-joalo.
AlN phofo e ka ntlafatsa haholo conductivity ea mocheso oa polasetiki.Ka ho eketsa Aluminium nitride nanoparticles ho polasetiki ho ea ka karolo ea 5% ~ 10% ka boima, re ka eketsa mocheso oa mocheso oa polasetiki ho tloha 0.3W / (mk) ho 0.5W / (mk), makhetlo a 16 ho feta.Ha ho bapisoa le mocheso conduction stuffing (alumina kapa magnesia) 'marakeng, e ka ntlafatsa thepa ea mechine ea lihlahisoa ka chelete e nyenyane.Hajoale, bahlahisi ba amanang ba rekile phofo ea AlN ka bongata mme polasetiki e ncha ea mofuta o mocha oa nano e tla hlahisoa 'marakeng.
AlN phofo e sebetsa hantle haholo ka silicon dioxide 'me e atisa ho hasana ka rabara.Tlas'a motheo oa ho se etse phapang ho ts'ebetso ea mochini oa rabara, (liteko li bontšitse hore e ka ntlafatsa ts'ebetso ea rabara), e ka ntlafatsa haholo mocheso oa mocheso oa rabara mme e ke ke ea theola viscosity joalo ka li-oxide tse ling nakong ea ho eketsa ts'ebetso. , 'me ho hlokahala chelete e nyenyane haholo.E 'nile ea sebelisoa haholo ho boenjiniere ba sesole, lifofane le boitsebiso.
