Lirolo tsa Alumina Ceramic: Likopo tse Feto-fetohang tse Matlafatsang Bokhabane ba Indasteri ba Mocheso o Phahameng

Tlhahisong ea mocheso o phahameng, tlhoko ea likarolo tse tšoarellang le tse tšepahalang ha e fetohe.Lirolo tsa letsopa tsa AluminaLi hlahella, li sebelisa thepa e ikhethang ho eketsa bokhoni ho pholletsa le liindasteri—ho tloha ho tempering ea khalase ho ea tlhahisong ea semiconductor. Likarolo tsena tse matla li hlalosa bocha ts'ebetso libakeng tse feteletseng. A re hlahlobeng lits'ebetso tsa tsona tsa bohlokoa tse etsang hore li be tsa bohlokoa bakeng sa tlhahiso ea sejoale-joale.
1. Tšebeliso ea mantlha: Li-Kilns tsa Tlhahiso ea Ceramic le Glass

Liindasteri tsa letsopa le khalase ke basebelisi ba mantlha, moo lirolara tsena li etsang mokokotlo oa litsamaiso tsa onto ea rola. Ka har'a lithaele tsa letsopa, lisebelisoa tsa bohloeki, le tlhahiso ea porcelain, li fetisa lihlahisoa ka ho chesa mocheso o phahameng (ho fihlela ho 1400°C+). Matla a tsona a phahameng a mocheso o phahameng le katoloso e tlase ea mocheso li thibela ho fetoha le ho sotha ha sehlahisoa, ho netefatsa boleng bo tsitsitseng.

Bakeng sa tlhahiso ea khalase (ho futhumatsa, ho annealing, ho qhibilihisa), li-roller tsa ceramic tsa alumina lia ipabola libakeng tsa ontong. Ho fapana le mekhoa e meng ea tšepe, li hanela ho bola ha khalase e qhibilihisitsoeng 'me li boloka botsitso bo boholo, li nolofalletsa ho tsamaisoa ha lakane ea khalase e boreleli ntle le tšilafalo - e leng ea bohlokoa bakeng sa tlhahiso ea khalase ea meralo le ea optical, ho eketsa chai le ho fokotsa nako ea ho sebetsa.

2. Kalafo ea Mocheso o Phahameng le Tšepe

Kalafo ea mocheso (ho annealing, ho tima, ho sintering) e hloka likarolo tse mamellang ho feto-fetoha ha mocheso le mocheso o feteletseng. Lirolo tsa ceramic tsa alumina li sebelisoa haholo ka har'a tšepe e seng ea ferrous (zinc, aluminium, koporo) le lifono tsa kalafo ea mocheso oa alloy. Khanyetso ea tsona e ntle ea ho phatloha ha mocheso (liphetoho tse potlakileng tsa 500°C) le khanyetso ea oxidation li etsa hore li be ntle bakeng sa ho tsamaisa mesebetsi ka mekhoa ena.

Ka hara metallurgy (ho qhibilihisa ntle le ferrous, ho sebetsana le diminerale), di sebetsa e le di-conveyor tse sa tsofaleng. Ka boima ba Mohs ba 9 (ba bobeli ho feta daemane), di hanela ho kgohlahala, di atolosa bophelo ba sesebediswa ho feta dirolara tsa tshepe tsa setso.

3. Tlhahiso ea Semiconductor le ea Elektroniki

Indasteri ea semiconductor e itšetlehile ka likarolo tse hloekileng haholo, tse nepahetseng haholo bakeng sa tlhahiso ea microchip. Lirolara tsa letsopa tsa alumina, tse nang le insulation e ikhethang ea motlakase (ho hanyetsa bophahamo ba modumo ho fihlela ho 10¹⁴Ω・cm) le litšila tse tlase, li sebelisoa ho sebetsana le wafer. Li nolofalletsa ho nepahala ha ho beha ±1μm, ho fokotsa tšilafalo le ho ntlafatsa chai ea chip.

Ho se sebetse ha tsona ka lik'hemik'hale ho boetse ho loketse lionto tsa elektroniki tse ntšang lintho tse chesang, tse fetisang likarolo tse bonolo (li-capacitor, li-resistor) ntle le lik'hemik'hale, e leng se etsang hore e be lintho tsa bohlokoa indastering.

4. Tlhahiso ea Matla a Macha le Libetri

Ha lefapha le lecha la eneji le ntse le hola, dirolara tsena di bohlokwa tlhahisong ya dibetri—ho tloha ho cathode/anode sintering ho ya kalafong ya mocheso wa sele. Di mamella 1600°C mme di hanela ho bola ha electrolyte, ha motlakase o tlase o netefatsa mocheso o tshwanang wa sebopi, ho netefatsa tshebetso ya betri le polokeho.

Li boetse li sebelisoa ts'ebetsong ea lisele tsa mafura a haedrojene, li hanela ho qhibiliha ha haedrojene le ho boloka botsitso mochesong o phahameng, li tšehetsa kholo ea matla a hloekileng.

5. Lisebelisoa tsa Lifofane le tsa ho Lokisa

Indasteri ea lifofane e ananela boima ba tsona bo bobebe (3.5g/cm³, halofo ea tšepe) le matla a tsona a phahameng, e li sebelisa kalafong ea mocheso oa enjene le mekhoeng ea sathelaete ho fokotsa boima ha ka nako e ts'oanang e boloka botšepehi, e eketsa ts'ebeliso ea mafura le bokhoni ba ho jara mojaro.

Ho disebediswa tse nepahetseng (tse bonahalang, tsa bongaka), ho nepahala ha tsona ha boemo ba micron (phoso ya bolelele ba ≤2μm bakeng sa dirolara tse 200mm) ho netefatsa tshebetso e boreleli. Biocompatibility e boetse e loketse tshebediso ya bongaka jwalo ka di-implant tsa meno.
