Boitsebiso bo Phahameng bakeng sa Likopo tse Hlokang

Safira ke mofuta o kang kristale oa aluminium oxide (Al₂O₃) 'me e behiloe ka tlase ho daemane ha ho tluoa tabeng ea boima, e fumana lintlha tse 9 sekaleng sa Mohs. Bohloko bona bo ikhethang bo etsa hore lipeipi tsa safire li hanele ho ngoapa, ho hohlana le ho tetebela ha mechini, esita le tlas'a tšebeliso e etsoang khafetsa kapa e matla.

Ka ntle ho matla a mechini, lipeipi tsa safire li ananeloa haholo ka lebaka la ho hanyetsa lik'hemik'hale tsa tsona. Li lula li tsitsitse ebile li sa sebetse hantle moo ho nang le li-acid tse ngata, li-solvents le likhase tse arabelang, ho kenyeletsoa le metsoako ea hydrogen fluoride, chlorine le sebabole. Sena se li lumella ho sebetsa ka katleho lits'ebetsong tse kenyelletsang lik'hemik'hale tse matla kapa plasma.

Ho phaella moo, tshebetso ya mocheso wa safire e makatsa. E mamella ho pepesehela mocheso ka nako e telele ho fihlela ho 2000°C ha e ntse e boloka botsitso ba sebopeho sa yona. Ho tsamaisa ha yona mocheso ho tshehetsa phetiso ya mocheso ka potlako, e leng tšobotsi ya bohlokwa haholo ha e sebediswa ditsamaisong tsa ho lemoha mocheso.

Molemo o mong oa bohlokoa ke ho pepeseha ha eona ha o bonaletsa mahlo ho pholletsa le maqhubu a ultraviolet, a bonahalang, le a infrared—ho tloha ho hoo e ka bang 0.3 μm ho isa ho 5 μm. Sena se etsa hore lipeipi tsa safire li lokele ho utloa mahlo kapa litsamaiso tse kopaneng tsa ho lekola mocheso le mahlo.

Li-thermocouple le Tlhokeho ea Tšireletso

Li-thermocouple ke likarolo tsa bohlokoa mefuteng e mengata ea litsamaiso, ho tloha ho liontong tsa tšepe le lienjine tsa turbine ho ea ho li-reactor tsa semiconductor le lisebelisoa tsa ts'ebetso ea lik'hemik'hale. Lisebelisoa tsena li hlahisa motlakase o ipapisitseng le phapang ea mocheso pakeng tsa litšepe tse peli tse fapaneng tse kopantsoeng pheletsong e le 'ngoe. Le hoja li-thermocouple li le matla ebile li le matla, ho pepesehela ha tsona mocheso ka ho toba, lintho tse senyang, le ho tšoha ha mechini ho ka khutsufatsa bophelo ba tsona ba ts'ebeletso haholo kapa ha fokotsa ho nepahala ha lipalo tsa mocheso.

Mona ke moo lipeipi tsa safire li sebetsang teng e le likhetla tse sireletsang. Ka ho koahela thermocouple ka har'a tube ea safire, sensor e aroloa tikolohong e thata ha e ntse e lumella phetiso e sebetsang hantle ea mocheso. Sephetho ke sensor e tšoarellang nako e telele, e tšepahalang haholoanyane e bolokang ho nepahala ho tsitsitseng esita le kamora ho pepesehela maemo a matla a ts'ebetso nako e telele.

Ho tsamaisa mocheso ha Sapphire ho dumella mocheso ho fihla ho thermocouple kapele le ka ho lekana, ho fokotsa ho dieha ha mocheso le ho ntlafatsa nako ya karabelo. Ho feta moo, ho hanyetsa ha yona tlhaselo ya dikhemikhale ho netefatsa hore sensor ha e senyehelwe ke masalla, mafome, kapa ho bokellana ha thepa—mathata ao hangata a hlaselang matsoho a sireletsang a tshepe kapa a letsopa.

Linyeoe tsa Tšebeliso ho Lekola Mocheso

Lifonong tse nang le mocheso o phahameng, lipeipi tsa safire li atisa ho sebelisoa ho sireletsa li-thermocouple tse behang leihlo maemo a bohlokoa a ts'ebetso. Ho tsitsa ha tsona ka lik'hemik'hale hoa hlokahala sepakapakeng se nang le likhase tse ngata tsa halogen, litšepe tse qhibilihisitsoeng, kapa mouoane o arabelang. Mohlala:

Tlhahiso ea Semiconductor: Li-sheath tsa sapphire li sireletsa li-thermocouple nakong ea kholo ea epitaxial, ho kenngoa ha wafer le lits'ebetso tsa doping, moo libaka tse hloekileng le taolo e nepahetseng ea mocheso li leng bohlokoa.
Li-reactor tsa lik'hemik'hale: Liketsahalong tsa catalytic kapa libakeng tsa mouoane o senyang, lipeipi tsa safire li netefatsa tšireletso ea nako e telele ea li-probe tsa mocheso, e leng se felisang matšoenyeho a tšilafalo.
Libeso tsa Vacuum: Liphaephe tsa sapphire li thibela oxidation le tšenyo ea mechini ho li-thermocouple ha li ntse li sebetsa tlas'a vacuum kapa likhase tse se nang khatello e tlase.
Mekhoa ea ho Chesa: Lienjine tsa jete, liturbine tsa khase, le li-burner tsa indasteri hangata li itšetleha ka li-thermocouple tse sirelelitsoeng ke safire ho lekola maemo a mocheso o feteletseng bakeng sa ts'ebetso le ntlafatso ea polokeho.

Ka ho sebelisa lipeipi tsa safire, baenjiniere ba khona ho kenya li-thermocouple maemong ao ho seng joalo a neng a tla ba kotsi haholo bakeng sa li-sheath tse tloaelehileng tsa tšepe kapa tsa khalase. Sena se atolosa mefuta e mengata ea ts'ebetso ea litsamaiso tsa tlhokomelo ea mocheso le ho ntlafatsa ts'ebetso ea tsona ea nako e telele.

Litšebeliso tse ling tsa indasteri tsa li-tube tsa Sapphire

Le hoja tshireletso ya thermocouple e le tshebediso e ka sehloohong, dipeipi tsa safire di sebediswa mahlaleng a mang a mangata a tswetseng pele:

Mabone a Phahameng a ho Hlahisa (HID): Jwalo ka thepa ya enfelopo, diphaephe tsa safire di mamella mocheso o matla le mahlaseli a UV/IR ntle le ho fifala kapa ho nolofala.
Likamore tsa ho Sebetsa ka Plasma: E sebelisoa e le libaka tsa ho shebella le ho thibela lijana ka lebaka la ho hanyetsa khoholeho ea mobu.
Ho lemoha ha Optical ka hare: E nolofalletsa tlhahlobo ea spectroscopy, litšoantšo, le laser ka liphaephe tsa ts'ebetso ntle le ho silafatsa mecha ea litaba.
Kalafo ea Metsi le Lisebelisoa tsa Bongaka: Ka lebaka la ho se sebetse hantle ha tsona 'meleng le ho hanyetsa lik'hemik'hale, lipeipi tsa safire li loketse litsamaiso tse hlokang ho se be le bohloeki le ho se sebetse hantle.
Mekhoa ea ho Fana ka Laser: Liphaephe tsa safira li tataisa mahlasedi a matla a phahameng ka tahlehelo e nyane ea optical le botsitso bo phahameng ba mocheso.

Lisebelisoa tsena li rua molemo ho tsoa litšobotsing tsa bohlokoa tsa safire—ho se sebetse hantle ha lik'hemik'hale, ho hlaka ha mahlo, ho thatafala ho hoholo le botsitso ba mocheso—ho pholletsa le liindasteri tse fapaneng joalo ka lifofane, tlhokomelo ea bophelo bo botle, lik'hemik'hale tsa peterole le lisebelisoa tsa elektroniki.
