Nthawi iliyonse tikamalankhula za beryllium oxide, choyamba chimati ndi poizoni kaya ndi kwa anthu osaphunzira kapena akatswiri. Ngakhale kuti beryllium oxide ndi poizoni, zinthu zomangira za beryllium oxide si poizoni.
Beryllium oxide imagwiritsidwa ntchito kwambiri m'magawo a zitsulo zapadera, ukadaulo wamagetsi opumira, ukadaulo wa nyukiliya, ma microelectronics ndi ukadaulo wa photoelectron chifukwa cha kutentha kwake kwakukulu, kutenthetsa kwambiri, kusinthasintha kochepa kwa dielectric, kutayika kwapakati kochepa, komanso kusinthasintha bwino kwa njira.
Zipangizo zamagetsi zamagetsi zamphamvu kwambiri komanso ma circuit ophatikizidwa
Kale, kafukufuku ndi chitukuko cha zipangizo zamagetsi zinkayang'ana kwambiri kapangidwe ka magwiridwe antchito ndi kapangidwe ka makina, koma tsopano chidwi chachikulu chikuperekedwa ku kapangidwe ka kutentha, ndipo mavuto aukadaulo a kutayika kwa kutentha kwa zipangizo zambiri zamagetsi amphamvu sanathe kuthetsedwa bwino. Beryllium oxide (BeO) ndi zinthu zadothi zokhala ndi conductivity yapamwamba komanso dielectric yotsika, zomwe zimapangitsa kuti zigwiritsidwe ntchito kwambiri m'munda waukadaulo wamagetsi.
Pakadali pano, zoumba za BeO zagwiritsidwa ntchito popanga ma microwave amphamvu kwambiri, ma transistor apaketi amagetsi amphamvu kwambiri, komanso ma multichip ambiri okhala ndi ma circuit density, ndipo kutentha komwe kumapangidwa mu dongosololi kumatha kuchotsedwa nthawi yake pogwiritsa ntchito zipangizo za BeO kuti zitsimikizire kukhazikika ndi kudalirika kwa dongosololi.
Reactor ya nyukiliya
Zipangizo za ceramic ndi chimodzi mwa zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito mu riyakitala ya nyukiliya. Mu ma reactor ndi ma converter, zipangizo za ceramic zimalandira kuwala kuchokera ku tinthu tamphamvu kwambiri komanso ma beta rays. Chifukwa chake, kuwonjezera pa kutentha kwambiri komanso kukana dzimbiri, zipangizo za ceramic zimafunikanso kukhala ndi kukhazikika kwa kapangidwe kake. Kuwunikira kwa neutron ndikuwongolera mafuta a nyukiliya nthawi zambiri kumapangidwa ndi BeO, B4C kapena graphite.
Kukhazikika kwa kuwala kwa dzuwa kwa beryllium oxide ceramics kutentha kwambiri kuli bwino kuposa chitsulo; kuchuluka kwake kuli kokwera kuposa beryllium chitsulo; mphamvu yake imakhala yabwinoko kutentha kwambiri; kutentha kwake kumakhala kokwera ndipo mtengo wake ndi wotsika kuposa beryllium chitsulo. Makhalidwe abwino onsewa amawapangitsa kukhala oyenera kugwiritsidwa ntchito ngati chowunikira, chowongolera, komanso chogawanitsa gawo la kutentha mu ma reactors. Beryllium oxide ingagwiritsidwe ntchito ngati ndodo zowongolera mu ma reactors a nyukiliya, ndipo ingagwiritsidwe ntchito limodzi ndi ma U2O ceramics ngati mafuta a nyukiliya.
Chophimba chapadera chachitsulo
Kwenikweni, BeO ceramics ndi zinthu zosagwira ntchito. Kuphatikiza apo, BeO ceramic crucible ingagwiritsidwe ntchito posungunula zitsulo zosowa ndi zitsulo zamtengo wapatali, makamaka pa chitsulo choyera kwambiri kapena alloy, komanso kutentha kwa ntchito ya crucible mpaka 2000 ℃. Chifukwa cha kutentha kwawo kosungunuka kwambiri (2550 ℃) komanso kukhazikika kwa mankhwala (alkali), kukhazikika kwa kutentha ndi kuyera, BeO ceramics ingagwiritsidwe ntchito popanga glaze yosungunuka ndi plutonium.
Mapulogalamu Ena
Ma ceramic a Beryllium oxide ali ndi kutentha kwabwino, komwe kuli kokwera kawiri kuposa quartz wamba, kotero laser ili ndi mphamvu zambiri komanso mphamvu yotulutsa.
Ma ceramic a BeO amatha kuwonjezeredwa ngati gawo la zinthu zosiyanasiyana zagalasi. Galasi yokhala ndi beryllium oxide, yomwe imatha kudutsa mu x-ray, imagwiritsidwa ntchito popanga machubu a X-ray omwe angagwiritsidwe ntchito pofufuza kapangidwe kake komanso kuchipatala pochiza matenda a pakhungu.
Ma ceramic a Beryllium oxide ndi osiyana ndi ma ceramic ena amagetsi. Pakadali pano, kutentha kwake kwakukulu komanso kutayika kochepa n'kovuta kusintha ndi zinthu zina. Chifukwa cha kufunika kwakukulu m'magawo ambiri asayansi ndi ukadaulo, komanso poizoni wa beryllium oxide, njira zotetezera ndizokhwima komanso zovuta, ndipo pali mafakitale ochepa padziko lonse lapansi omwe angapange ma ceramic a beryllium oxide mosamala.
Zothandizira pa Ufa wa Beryllium Oxide
Monga kampani yopanga ndi kugulitsa zinthu ku China, UrbanMines Tech Limited imadziwika kwambiri ndi Beryllium Oxide Powder ndipo imatha kupanga mtundu wa purity grade womwe ndi 99.0%, 99.5%, 99.8% ndi 99.9%. Pali malo opezeka a grade 99.0% ndipo amapezeka kuti agwiritsidwe ntchito ngati zitsanzo.
