Beryllium oxide ceramics oo leh kuleyl heer sare ah iyo sifooyin lumis hoose
BeO ceramics waxaa hadda loo isticmaalaa wax qabad sare, baakadaha mikrowave ee awoodda sare leh, xirmooyinka koronto-sidaha elektiroonigga ah ee soo noqnoqda, iyo qaybaha cufnaanta wareegga-sare ee qaybaha-chip-yada badan. Isticmaalka walxaha BeO waxay baabi'in kartaa kuleylka ka soo baxa nidaamka wakhtiga si loo hubiyo xasilloonida iyo kalsoonida nidaamka.
BeO loo isticmaalo baakadaha transistor-ka elektiroonigga ah ee soo noqnoqda
Fiiro gaar ah: Transistor waa qalab semiconductor adag ah, oo leh ogaanshaha, hagaajinta, kordhinta, beddelka, nidaaminta tamarta, habaynta calaamadaha iyo hawlo kale. Nooc ka mid ah beddelka hadda jira, transistor-ku wuxuu xakameyn karaa wax soo saarka hadda iyadoo lagu saleynayo tamarta wax gelinta. Si ka duwan shixnadaha farsamada ee caadiga ah, transistor-yadu waxa ay isticmaalaan isgaadhsiin si ay u xakameeyaan furista iyo xidhidhahooda, xawaaruhuna waxa uu noqon karaa mid aad u dheereeya, xawaaraha beddelka ee shaybaarku waxa uu gaadhi karaa in ka badan 100GHz.
Codsiga Ka-hortagga Nukliyeerka
Qalabka Nuclear-ka Nukliyeerka ah ee Nukliyeerka ah waa mid ka mid ah qalabka muhiimka ah ee loo isticmaalo reactors, reactors iyo reactors fusion, alaabta dhoobada waxay helayaan qaybo tamar sare leh iyo shucaaca gamma, sidaas darteed, marka lagu daro iska caabbinta heerkulka sare, caabbinta daxalka, alaabta dhoobada waxay sidoo kale u baahan yihiin inay yeeshaan wanaagsan xasilloonida qaab dhismeedka. Miliciyeyaasha neutron-ka iyo dhexdhexaadiyeyaasha (moderators) ee shidaalka nukliyeerka ayaa badanaa ah BeO, B4C ama walxaha garaafka.
Ceramics Beryllium oxide waxay leeyihiin xasillooni shucaac heerkul sarreeya oo ka wanaagsan birta, cufnaanta ka sarreysa birta beryllium, xoog ka fiican heerkulka sare, kuleylka kuleylka sarreeya, iyo ka jaban birta beryllium. Waxa kale oo ay ku habboon tahay in loo isticmaalo sidii muraayad, dhexdhexaadiye iyo weji kala firdhiso wadar ahaan gubasho ahaan. Beryllium oxide waxaa loo isticmaali karaa sidii usha kantaroolka ee reactors nukliyeerka, waxaana lagu dari karaa dhoobada U2O si ay u noqoto shidaal nukliyeer ah.
Dib-u-soo-celinta Fasalka Sare - Qalab Bir ah oo Gaar ah
Alaabta dhoobada BeO waa walxo soo celinaysa. BeO ceramic crucibles waxaa loo isticmaali karaa in lagu dhalaaliyo biraha qaaliga ah iyo kuwa dhifka ah, gaar ahaan halka loo baahan yahay biraha nadiifka ah ama alwaaxyada. Heerkulka shaqada ee crucible wuxuu gaari karaa 2000 ℃.
Sababo la xiriira heerkulka dhalaalaysa sare (qiyaastii 2550 ° C), xasiloonida kiimikada sare (alkali caabbinta), xasiloonida kulaylka iyo daahirsanaanta, BeO ceramics waxaa loo isticmaali karaa in ay dhalaaliso glazes iyo plutonium. Intaa waxaa dheer, crucibles, kuwaas oo si guul leh loo isticmaalay si loo soo saaro muunado caadiga ah ee qalin, dahab iyo platinum. Heerka sare ee "daah-furnaanta" ee BeO ilaa shucaaca korantada ayaa u oggolaanaysa shaybaarada birta in lagu dhalaaliyo kuleyliyaha induction.
Codsiga Kale
a. Ceramics Beryllium oxide waxay leeyihiin kulayl wanaagsan, taas oo ah laba amar oo ka sarreeya quartz inta badan la isticmaalo, sidaas darteed laserku wuxuu leeyahay waxtar sare iyo awood wax soo saar oo weyn.
b. BeO ceramics waxaa lagu dari karaa qayb ahaan galaas ka kooban noocyo kala duwan. Muraayad ka kooban beryllium oxide oo gudbiya raajada. Tuubooyinka raajada ee muraayaddan laga sameeyay ayaa loo isticmaalaa falanqaynta qaabdhismeedka iyo daawada lagu daweeyo cudurrada maqaarka.
Beryllium oxide ceramics iyo dhoobada kale ee elektiroonigga ah way kala duwan yihiin, ilaa hadda, heerkulka sare ee kuleylka iyo sifooyinka hooseeya way adagtahay in lagu beddelo qalab kale.
