Txhua zaus thaum peb tham txog beryllium oxide, thawj qhov kev xav yog tias nws muaj tshuaj lom txawm tias nws yog rau cov neeg nyiam ua si lossis cov kws tshaj lij. Txawm hais tias beryllium oxide muaj tshuaj lom, beryllium oxide ceramics tsis muaj tshuaj lom.
Beryllium oxide yog siv dav hauv cov teb ntawm kev siv tshuab tshwj xeeb, tshuab nqus tsev hluav taws xob, tshuab nuclear, microelectronics thiab photoelectron vim nws cov thermal conductivity siab, rwb thaiv tsev siab, dielectric tsis tu ncua qis, poob nruab nrab qis, thiab cov txheej txheem hloov kho tau zoo.
Cov khoom siv hluav taws xob muaj zog heev thiab cov voj voog sib xyaw ua ke
Yav dhau los, kev tshawb fawb thiab kev tsim kho cov khoom siv hluav taws xob feem ntau tsom mus rau kev tsim qauv kev ua tau zoo thiab kev tsim qauv mechanism, tab sis tam sim no ntau qhov kev saib xyuas tau them rau kev tsim thermal, thiab cov teeb meem kev siv tshuab ntawm kev poob thermal ntawm ntau lub zog siab tsis tau daws zoo. Lub beryllium oxide (BeO) yog cov khoom siv ceramic nrog kev ua tau zoo thiab dielectric 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 siab microwave ntim, lub zog siab transistor hluav taws xob ntim, thiab cov khoom siv high-circuit density multichip, thiab cov cua sov tsim tawm hauv lub kaw lus tuaj yeem raug tshem tawm raws sijhawm los ntawm kev siv BeO cov ntaub ntawv kom ntseeg tau tias lub kaw lus ruaj khov thiab kev ntseeg siab.
Lub chaw tsim hluav taws xob nuclear
Cov khoom siv ceramic yog ib qho ntawm cov khoom siv tseem ceeb tshaj plaws uas siv hauv lub nuclear reactor. Hauv cov reactors thiab converters, cov khoom siv ceramic tau txais hluav taws xob los ntawm cov khoom me me thiab beta rays. Yog li ntawd, ntxiv rau qhov kub thiab txias thiab kev tiv thaiv corrosion, cov khoom siv ceramic kuj tseem yuav tsum muaj kev ruaj khov zoo dua. Qhov kev cuam tshuam neutron thiab moderator ntawm cov roj nuclear feem ntau yog ua los ntawm BeO, B4C lossis graphite.
Qhov ruaj khov ntawm kev kub siab ntawm beryllium oxide ceramics zoo dua li hlau; qhov ceev yog siab dua li beryllium hlau; lub zog zoo dua nyob rau hauv qhov kub siab; qhov kev coj ua cua sov yog siab thiab tus nqi pheej yig dua li beryllium hlau. Tag nrho cov yam ntxwv zoo heev no ua rau nws tsim nyog dua rau kev siv ua lub teeb ci, lub moderator, thiab cov khoom sib xyaw ua ke hauv cov reactors. Beryllium oxide tuaj yeem siv ua cov pas nrig tswj hauv cov reactors nuclear, thiab nws tuaj yeem siv ua ke nrog U2O ceramics ua roj nuclear.
Cov khoom siv hlau tshwj xeeb
Qhov tseeb, BeO ceramics yog cov khoom siv refractory. Tsis tas li ntawd, BeO ceramic crucible tuaj yeem siv rau hauv kev yaj ntawm cov hlau tsis tshua muaj thiab cov hlau muaj nqis, tshwj xeeb tshaj yog nyob rau hauv cov hlau lossis alloy uas xav tau kev ntshiab siab, thiab qhov kub ua haujlwm ntawm crucible txog li 2000 ℃. Vim lawv qhov kub yaj siab (2550 ℃) thiab kev ruaj khov tshuaj lom neeg siab (alkali), kev ruaj khov thermal thiab kev ntshiab, BeO ceramics tuaj yeem siv rau cov molten glaze thiab plutonium.
Lwm Cov Ntawv Thov
Beryllium oxide ceramics muaj cov thermal conductivity zoo, uas yog ob qho kev txiav txim siab ntawm qhov siab dua li cov quartz feem ntau, yog li lub laser muaj kev ua haujlwm siab thiab lub zog tso zis siab.
Cov khoom siv ua los ntawm BeO tuaj yeem ntxiv ua ib feem ntawm ntau yam khoom siv ntawm iav. Cov iav uas muaj beryllium oxide, uas tuaj yeem hla dhau cov duab xoo hluav taws xob, yog siv los ua cov raj duab xoo hluav taws xob uas tuaj yeem siv rau kev tshuaj xyuas cov qauv thiab kev kho mob los kho cov kab mob ntawm daim tawv nqaij.
Beryllium oxide ceramics txawv ntawm lwm cov khoom siv hluav taws xob. Txog tam sim no, nws cov thermal conductivity siab thiab cov yam ntxwv poob qis nyuaj rau hloov los ntawm lwm cov ntaub ntawv. Vim muaj kev thov siab hauv ntau qhov kev tshawb fawb thiab thev naus laus zis, nrog rau qhov lom ntawm beryllium oxide, cov kev ntsuas tiv thaiv yog qhov nruj heev thiab nyuaj, thiab muaj ob peb lub Hoobkas hauv ntiaj teb uas tuaj yeem tsim cov beryllium oxide ceramics tau zoo.
Kev Muab Khoom Siv Rau Beryllium Oxide Hmoov
Ua ib lub tuam txhab tsim khoom thiab muag khoom hauv Suav teb, UrbanMines Tech Limited tshwj xeeb hauv Beryllium Oxide Hmoov thiab tuaj yeem ua kom tau qib purity raws li 99.0%, 99.5%, 99.8% thiab 99.9%. Muaj cov khoom lag luam rau qib 99.0% thiab muaj rau kev kuaj.
