Ho sa le jwalo, tshebediso ya phofo ya alumina e chitja le phofo ya submicron lefapheng la diseramike tsa meaho e ntse e eketseha, ka lebaka la ho phalla ha tsona hantle le ho tsitsisa ha tsona.
Ⅲ. Boleng ba Theknoloji ho Lisebelisoa tsa Elektronike le tsa Motlakase
Liserame tsa elektroniki ke e 'ngoe ea masimo a tlase a nang le bokhoni bo boholo ba ho eketsa phofo ea alumina. Liserame tsa alumina li na le thepa e ntle ea ho thibela le ho thibela dielectric, e leng se etsang hore li lokele li-substrate tsa ho paka tsa potoloho e kopaneng, li-insulator tse nang le maqhubu a phahameng, li-substrate tse senyang mocheso, le likarolo tsa ho thibela matla. Nts'etsopele e potlakileng ea lisebelisoa tsa elektroniki tsa motlakase le puisano ea maqhubu a phahameng e tsamaisitse ntlafatso e tsoelang pele ea tahlehelo ea dielectric le ho tsamaisa mocheso oa thepa ea substrate ea ceramic. Li-substrate tsa ceramic tsa alumina tse hloekileng haholo li fetohile thepa ea bohlokoa haholo li-module tsa motlakase le masimong a semiconductor.
Lefapheng la di-substrate tsa ho qhala ha mocheso wa LED, di-substrate tsa letsopa tse entsweng ka phofo ya alumina di na le bokgoni bo botle ba ho tsamaisa mocheso le thepa ya ho thibela motlakase, tse fanang ka tshehetso e tshepahalang bakeng sa diphutheloana tsa LED tse matla haholo. Ka tlhahiso e kgolo ya dikoloi tse ntjha tsa matla, di-pile tsa ho tjhaja, le disebediswa tsa ho boloka matla, tlhokeho ya disebediswa tsa letsopa tsa disebediswa tsa motlakase e kene potolohong ya kgolo, e tlisang menyetla e tsitsitseng le ya nako e telele ya mmaraka bakeng sa phofo ya alumina.
Ⅳ. Melemo ea Setso ho Refractory le Catalytic Ceramics
Lisebelisoa tsa setso tse hanyetsang mocheso e ntse e le sebaka sa bohlokoa sa ts'ebeliso bakeng sa phofo ea alumina. Ka lebaka la ntlha ea eona e phahameng ea ho qhibiliha le ho hanyetsa ho bola ha lik'hemik'hale ka matla, phofo ea alumina e ka sebelisoa ho etsa li-lining tsa sebōpi tse mocheso o phahameng, li-crucible, litene tsa nozzle, le likarolo tsa ho kopana le tšepe e qhibilihisitsoeng. Liindasteri tse futhumatsang mocheso o phahameng tse kang tšepe, litšepe tse se nang ferrous, le tlhahiso ea wafer ea potoloho e kopaneng e ntse e le basebelisi ba ka sehloohong ba li-ceramic tse hanyetsang mocheso oa alumina.
Tšimo e 'ngoe e hōlileng ke li-ceramic tsa catalytic carrier, tse kang li-ceramic tsa mahe a linotši le li-catalytic carrier tsa alumina. Sebaka se ikhethileng sa bokaholimo le sebopeho se nang le masoba aphofo ea aluminali fana ka motheo o motle oa ho khomarela bakeng sa likarolo tse sebetsang tsa catalytic, 'me li sebelisoa haholo kalafong ea mosi oa likoloi, ho petsoha ha catalytic ea fektheri, le litsamaisong tsa ho tlosa nitrification tikolohong.
Ⅴ. Ntlafatso ea Litsela tsa Ts'ebetso le Litsela tsa Theknoloji ea Liindasteri
Ka ntlafatso ea theknoloji ea indasteri ea letsopa, bahlahisi ba phofo ea alumina ba ntse ba fetoha ho tloha mekhoeng ea setso ea ho nosetsa lik'hemik'hale ho ea ho fafatsa ka ho fafatsa, ho hatella ka isostatic, ho kenya plasma ka thermal spheroidization, le mahlale a ho fetola bokaholimo. Ka lehlakoreng le leng, boholo ba likaroloana tse tšesaane le phofo e hloekileng e phahameng li ntlafatsa ts'ebetso ea ho sintering ka linako tsohle; ka lehlakoreng le leng, mahlale a ho fetola a ntlafatsa ho lumellana ha phofo le li-binder le litsamaiso tsa solvent, ho nolofatsa taolo ea rheological ea slurry ea letsopa le ho enta ka ente. Hoa hlokomeleha hore lilemong tsa morao tjena, tlhoko ea ts'ebetso ea mechini indastering ea letsopa e eketsehile ka nako e le 'ngoe. Ntlafatso ea ho nepahala ha ts'ebetso ea bokaholimo ba letsopa e lebisitse ho sebopeho se tloaelehileng sa likaroloana tsa phofo, 'me phofo ea alumina e chitja e kene masimong a ho bentša ha optical le tlhahiso ea wafer, e tlisa lintlha tse ncha tsa kholo ea phaello bakeng sa lik'hamphani tsa phofo.
Ⅵ. Mekhoa ea Indasteri: Ntlafatso ea Lintho e Hlohlelletsa Liphetoho Sebakeng sa 'Maraka
Ka lebaka la mekhoa ea thepa ea "boima bo bobebe, ts'ebetso e phahameng, le ho kenngoa ha li-elektronike," li-ceramic tse sebetsang hantle li ntse li fumana boemo bo phahameng ba maano. Meralo ea theknoloji ea indasteri ea likoloi, ea bongaka, ea matla le ea semiconductor e khetholla tataiso ea ts'ebeliso ea phofo ea alumina nakong e tlang.
Mekhoa ea indasteri ea hona joale e bontša litšobotsi tse tharo tsa bohlokoa:
① Lisebelisoa tsa mocheso o phahameng le indasteri e ncha ea matla li eketsa tlhoko ea li-ceramic tse sa tsofaleng le tse thibelang mocheso;
② Liserame tsa elektroniki li fetoha mohloli oa tlhoko e eketsehileng ea phofo e hloekileng haholo;
③ Ho ntlafatsa boholo ba likaroloana, ntlafatso ea bohloeki, le botsitso ba karolo ea kristale li fetoha motheo oa tlholisano ea phofo.
Lefatše ka bopharaindasteri ea letsopaHona jwale ketane e maemong a tlholisano a nang le mekhahlelo. Dikhamphani tsa phofo ya maemo a hodimo di na le monyetla wa theknoloji masimong a di-elektroniki le a di-semiconductor, ha phofo ya maemo a mahareng e ntse e shebane haholo le di-ceramic tsa meaho le thepa e hanyetsang. Ka lebaka la tlhokeho e theohelang tlase, mmaraka wa phofo ya maemo a mahareng ho isa ho a hodimo o lebelletswe ho boloka kgolo.
