ILanthanum Hexaboride LaB6 Nanoparticles
Lanthanum Hexaboride I-LaB6 Nanoparticles
Lanthanum hexaboride, umgubo omfusa, ubuninzi be-2.61g / cm3, i-melting point 2210 °C, ukubola ngaphezu kwendawo yokunyibilika. I-insoluble emanzini kunye ne-asidi kwiqondo lokushisa. Ngenxa yeempawu zendawo yokunyibilika ephezulu kunye nokusebenza okuphezulu kwe-electron yobushushu bemitha ye-elektroni, inokungena endaweni yeendawo eziphezulu zokunyibilika zesinyithi kunye ne-alloys kwiireactor zokudityaniswa kwenyukliya kunye nokuveliswa kwamandla e-thermoelectronic.
Isalathiso
| Inombolo yemveliso | D50 (nm) | Ucoceko(%) | Indawo ethile yomphezulu (m2/g) | Ubuninzi bobuninzi (g/cm3) | Ubuninzi (g/cm3） | Ipolymorph | Umbala |
| LaB6-01 | 100 | >99.9 | 21.46 | 0.49 | 4.7 | Ityhubhu | Mfusa |
| LaB6-02 | 1000 | >99.9 | 11.77 | 0.89 | 4.7 | Ityhubhu | Mfusa |
Ulwalathiso lwesicelo
1. Inoluhlu olubanzi lokusetyenziswa, kwaye isetyenziswe ngempumelelo kwiindawo ezingaphezu kwe-20 zomkhosi kunye nobuchwepheshe obuphezulu njenge-radar, i-aerospace, i-electronic industry, i-instrumentation, izixhobo zonyango, i-metallurgy yesixhobo sasekhaya, ukukhuselwa kwendalo, njl. ,lanthanum hexaborideIkristale enye yinto yokwenza iityhubhu ze-electron zamandla aphezulu, iimagnethi, imiqadi ye-electron, imiqadi ye-ion, kunye ne-accelerator cathodes;
2. Nanoscale lanthanum boridesisigqubuthelo esifakwa kumphezulu wefilimu yepolyethylene ukwahlula imitha ye-infrared yokukhanya kwelanga. I-Nanoscale lanthanum boride ifunxa ukukhanya kwe-infrared ngaphandle kokufunxa ukukhanya okubonakalayo. Ngokwezifundo zamva nje, i-resonance peak ye-nanoscale lanthanum boride inokufikelela kwi-nanometers eyi-1000, kwaye ubude be-absorption buphakathi kwe-750 kunye ne-1300.
3. Nanoscale lanthanum borideyimathiriyeli ye-nano-coating yeglasi yefestile. Iingubo ezenzelwe imozulu eshushu zivumela ukukhanya okubonakalayo ukuba kudlule kwiglasi, kodwa kuthintele imitha ye-infrared ukuba ingangeni. Kwiindawo ezibandayo, i-nanocoatings inokwenza ukusetyenziswa ngokufanelekileyo kokukhanya kunye namandla obushushu ngokuthintela ukukhanya kunye nobushushu ukuba buphinde bubuyele ngaphandle.
Iimeko zokugcina
Le mveliso kufuneka itywinwe kwaye igcinwe kwindawo eyomileyo nepholileyo, ayifanelekanga ukubonakaliswa kwexesha elide emoyeni, ukukhusela i-agglomeration ngokufuma, echaphazela ukusebenza kwe-dispersion kunye nesiphumo sokusetyenziswa, kwaye kufuneka igweme uxinzelelo olunzima, ungaqhagamshelani ne-oxidants. , kwaye zihanjiswe ngokwempahla eqhelekileyo.
