Beryllium oxide ceramics e nang le conductivity e phahameng ea mocheso le litšobotsi tse tlaase tsa tahlehelo
Li-ceramics tsa BeO hajoale li sebelisoa ka har'a liphutheloana tsa microwave tse sebetsang hantle haholo, tse nang le matla a phahameng, liphutheloana tsa transistor tsa elektronike tsa maqhubu a phahameng, le likaroloana tsa li-chip tse ngata. Tšebeliso ea thepa ea BeO e ka senya mocheso o hlahisoang tsamaisong ka nako ho netefatsa botsitso le ho tšepahala ha tsamaiso.
BeO e sebelisetsoa liphutheloana tse phahameng tsa elektroniki tsa transistor
Tlhokomeliso: Transistor ke sesebelisoa se tiileng sa semiconductor, se nang le ho lemoha, ho lokisa, ho phahamisa, ho fetola, ho laola motlakase, ho feto-fetoha ha molumo le mesebetsi e meng. Joalo ka mofuta oa switch ea hajoale e feto-fetohang, transistor e khona ho laola tlhahiso ea hona joale e ipapisitseng le matla a kenang. Ho fapana le li-switches tse tloaelehileng tsa mochini, li-transistors li sebelisa likhokahano tsa mehala ho laola ho bula le ho koala ha tsona, 'me lebelo la ho switjha le ka potlaka haholo,' me lebelo la ho chencha ka laboratoring le ka fihla ho feta 100GHz.
Tšebeliso ho Li-reactors tsa Nyutlelie
Lisebelisoa tsa ceramic tsa nyutlelie ke e 'ngoe ea lisebelisoa tsa bohlokoa tse sebelisoang ho li-reactors, ho li-reactors le fusion reactors, lisebelisoa tsa ceramic li fumana likaroloana tse phahameng tsa matla le mahlaseli a gamma, ka hona, ntle le mocheso o phahameng oa ho hanyetsa, ho hanyetsa kutu, lisebelisoa tsa ceramic le tsona li hloka ho ba le molemo. botsitso ba sebopeho. Lisebelisoa tsa nyutrone le balaoli (baokameli) ba mafura a nyutlelie hangata ke BeO, B4C kapa thepa ea graphite.
Li-ceramics tsa Beryllium oxide li na le botsitso bo betere ba mocheso o phahameng oa mocheso ho feta tšepe, boima bo phahameng ho feta tšepe ea beryllium, matla a molemo mocheso o phahameng, mocheso o phahameng oa mocheso, 'me o theko e tlaase ho feta tšepe ea beryllium. E boetse e loketse ho sebelisoa e le sebonela-hōle, molekanyetsi le sehlopha sa ho chesa mohato oa ho qhala ka har'a mochine o motlakase. Beryllium oxide e ka sebelisoa joalo ka lere la taolo ho li-reactors tsa nyutlelie, 'me e ka kopanngoa le lirafshoa tsa U2O ho fetoha mafura a nyutlelie.
High-Grade Refractory - Special Metallurgical Crucible
Sehlahisoa sa BeO ceramic ke thepa e refractory. Li-crucible tsa BeO ceramic crucibles li ka sebelisoa ho qhibilihisa lirafshoa tse sa tloaelehang le tsa bohlokoa, haholo-holo moo ho hlokahalang litšepe tse hloekileng kapa li-alloys. Mocheso o sebetsang oa crucible o ka fihla ho 2000 ℃.
Ka lebaka la mocheso oa eona o phahameng oa ho qhibiliha (hoo e ka bang 2550 ° C), botsitso bo phahameng ba lik'hemik'hale (ho hanyetsa alkali), botsitso le bohloeki ba mocheso, li-ceramics tsa BeO li ka sebelisoa ho qhibilihisa likhalase le plutonium. Ho phaella moo, li-crucibles tsena li 'nile tsa sebelisoa ka katleho ho hlahisa lisampole tse tloaelehileng tsa silevera, khauta le platinum. Boemo bo phahameng ba "transparency" ea BeO ho radiation ea motlakase e lumella lisampole tsa tšepe hore li qhibilihe ka ho futhumala ha induction.
Tšebeliso e 'ngoe
a. Li-ceramics tsa Beryllium oxide li na le conductivity e ntle ea mocheso, e leng li-oda tse peli tsa boholo bo phahameng ho feta quartz e sebelisoang hangata, kahoo laser e na le ts'ebetso e phahameng le matla a maholo a tlhahiso.
b. Li-ceramics tsa BeO li ka eketsoa e le karolo ea likhalase tsa lipina tse fapaneng. Khalase e nang le beryllium oxide e fetisang mahlaseli a X. Li-tubes tsa X-ray tse entsoeng ka khalase ena li sebelisoa ho hlahloba sebopeho le meriana ho phekola mafu a letlalo.
Li-ceramics tsa Beryllium oxide le li-ceramics tse ling tsa elektronike li fapane, ho fihlela joale, ho thata ho nkeloa sebaka ke lisebelisoa tse ling tse phahameng tsa mocheso le litšoaneleho tse tlaase tsa tahlehelo.
