Txhua zaus thaum peb tham txog beryllium oxide, thawj cov tshuaj tiv thaiv yog tias nws yog tshuaj lom txawm tias nws yog rau cov neeg nyiam ua haujlwm lossis cov kws tshaj lij. Txawm hais tias beryllium oxide yog tshuaj lom, beryllium oxide ceramics tsis muaj tshuaj lom.
Beryllium oxide yog siv dav hauv kev lag luam tshwj xeeb metallurgy, nqus hluav taws xob thev naus laus zis, thev naus laus zis nuclear, microelectronics thiab photoelectron technology vim nws cov thermal conductivity, siab rwb thaiv tsev, tsis tshua muaj hluav taws xob tas li, tsis tshua muaj nruab nrab poob, thiab cov txheej txheem zoo adaptability.
Cov khoom siv hluav taws xob muaj zog siab thiab kev sib xyaw ua ke
Yav dhau los, kev tshawb fawb thiab kev loj hlob ntawm cov khoom siv hluav taws xob feem ntau yog tsom rau kev tsim qauv thiab kev tsim qauv, tab sis tam sim no ntau cov kev xav tau them rau thermal tsim, thiab cov teeb meem kev thermal poob ntawm ntau lub zog hluav taws xob tsis zoo daws tau. Lub beryllium oxide (BeO) yog cov khoom siv ceramic nrog cov khoom siv hluav taws xob siab thiab tsis tshua muaj hluav taws xob tsis tu ncua, uas ua rau nws siv dav hauv kev siv tshuab hluav taws xob.
Tam sim no, BeO ceramics tau siv rau hauv kev ua haujlwm siab, lub zog loj microwave ntim, cov khoom siv hluav taws xob ntau zaus, thiab cov khoom siv hluav taws xob ntau ntau, thiab cov cua sov tsim hauv lub cev tuaj yeem raug tshem tawm raws sijhawm los ntawm kev siv BeO cov ntaub ntawv rau xyuas kom muaj kev ruaj ntseg thiab kev cia siab ntawm qhov system.
Nuclear reactor
Cov khoom siv ceramic yog ib qho ntawm cov khoom tseem ceeb tshaj plaws uas siv hauv lub tshuab hluav taws xob nuclear. Hauv reactors thiab converters, cov ntaub ntawv ceramic tau txais hluav taws xob los ntawm cov khoom siv hluav taws xob siab thiab beta rays. Yog li ntawd, ntxiv rau qhov kub thiab txias tsis kam, cov ntaub ntawv ceramic kuj yuav tsum muaj kev ruaj ntseg zoo dua. Lub neutron reflection thiab moderator ntawm nuclear roj feem ntau yog ua los ntawm BeO, B4C los yog graphite.
Lub high-temperature irradiation stability ntawm beryllium oxide ceramics yog zoo dua li hlau; qhov ceev yog siab tshaj beryllium hlau; lub zog yog zoo dua nyob rau hauv high kub; Thaum tshav kub kub conductivity yog siab thiab tus nqi yog pheej yig dua beryllium hlau. Tag nrho cov khoom zoo no ua rau nws tsim nyog rau kev siv los ua ib qho kev cuam tshuam, tus neeg saib xyuas, thiab cov txheej txheem sib cais sib cais hauv cov reactors. Beryllium oxide tuaj yeem siv los tswj cov pas nrig hauv nuclear reactors, thiab nws tuaj yeem siv ua ke nrog U2O ceramics li roj nuclear.
Tshwj xeeb metallurgical crucible
Qhov tseeb, BeO ceramics yog cov khoom siv refractory. Tsis tas li ntawd, BeO ceramic crucible tuaj yeem siv rau hauv kev sib tsoo ntawm cov hlau tsis tshua muaj thiab cov hlau muaj txiaj ntsig, tshwj xeeb tshaj yog nyob rau hauv qhov xav tau cov hlau purity siab lossis alloy, thiab qhov kub thiab txias ntawm lub crucible mus txog 2000 ℃. Vim lawv cov kub melting kub (2550 ℃) thiab siab chemical stability (alkali), thermal stability thiab purity, BeO ceramics yuav siv tau rau molten glaze thiab plutonium.
Lwm Daim Ntawv Thov
Beryllium oxide ceramics muaj cov thermal conductivity zoo, uas yog ob qhov kev txiav txim siab ntau dua li cov quartz, yog li lub laser muaj kev ua haujlwm siab thiab siab tso zis zog.
BeO ceramics tuaj yeem muab ntxiv ua cov khoom siv hauv ntau yam iav. Cov iav uas muaj beryllium oxide, uas tuaj yeem dhau los ntawm x-rays, yog siv los ua X-ray raj uas tuaj yeem siv rau kev txheeb xyuas cov qauv thiab kev kho mob los kho cov kab mob ntawm daim tawv nqaij.
Beryllium oxide ceramics txawv ntawm lwm yam hluav taws xob ceramics. Txog tam sim no, nws cov thermal conductivity siab thiab cov yam ntxwv poob qis yog qhov nyuaj los hloov los ntawm lwm cov ntaub ntawv. Vim tias qhov kev thov siab hauv ntau qhov kev tshawb fawb thiab thev naus laus zis, nrog rau cov tshuaj lom ntawm beryllium oxide, kev tiv thaiv kev tiv thaiv yog nruj heev thiab nyuaj, thiab muaj ob peb lub Hoobkas hauv ntiaj teb uas tuaj yeem tsim cov beryllium oxide ceramics zoo.
Muab Kev Pabcuam rau Beryllium Oxide Powder
Raws li ib tus kws tshaj lij Suav Chaw Tsim Khoom thiab Chaw Muag Khoom, UrbanMines Tech Limited yog tshwj xeeb hauv Beryllium Oxide Powder thiab tuaj yeem ua raws li qib purity li 99.0%, 99.5%, 99.8% thiab 99.9%. Muaj cov khoom lag luam rau 99.0% qib thiab muaj rau kev kuaj.
