Beryllium oxide ceramics ine yakakwira yekupisa conductivity uye yakaderera kurasikirwa maitiro
BeO Ceramics parizvino inoshandiswa mukuita kwepamusoro-soro, yakakwirira-simba microwave mapakeji, yakakwirira-frequency yemagetsi transistor mapakeji, uye yakakwirira-yedunhu density akawanda-chip zvikamu. Kushandiswa kwezvinhu zveBeO zvinogona kubvisa kupisa kunogadzirwa muhurongwa munguva kuti ive nechokwadi chekugadzikana uye kuvimbika kwehurongwa.
BeO inoshandiswa kune yakakwirira-frequency yemagetsi transistor packaging
Ongorora: Transistor yakasimba semiconductor mudziyo, ine kuona, kugadzirisa, kuwedzera, switching, voltage regulation, chiratidzo modulation uye mamwe mabasa. Semhando yekuchinjika ikozvino switch, iyo transistor inogona kudzora inobuda ikozvino zvichienderana neiyo voltage yekupinza. Kusiyana neakajairwa machinjo emuchina, ma transistors anoshandisa nhare kudzora kuvhura nekuvhara kwavo, uye kumhanya kwekuchinja kunogona kukurumidza kwazvo, uye kumhanya kwekuchinja murabhoritari kunogona kusvika kupfuura 100GHz.
Kushandiswa MuNuclear Reactors
Nuclear reactor ceramic material ndechimwe chezvinhu zvakakosha zvinoshandiswa mumareactors, mumareactors uye fusion reactors, ceramic zvinhu zvinogamuchira yakakwirira-simba zvidimbu uye gamma radiation, saka, mukuwedzera kune yakakwira tembiricha kuramba, corrosion resistance, ceramic zvinhu zvinodawo kuva zvakanaka. kugadzikana kwemaitiro. Maneutron reflectors uye moderators (moderator) emafuta enyukireya anowanzova BeO, B4C kana graphite zvinhu.
Beryllium oxide ceramics ine kugadzikana kwekushisa kwemagetsi kuri nani kupfuura simbi, kusimba kwepamusoro pane simbi yeberyllium, kusimba kuri nani pakupisa kwakanyanya, kukwira kwekushisa kwemhepo, uye kuchipa kupfuura simbi yeberyllium. Inokodzerawo kushandiswa se reflector, moderator uye dispersion phase combustion pamwe chete mu reactor. Beryllium oxide inogona kushandiswa semudonzvo wekudzora mumagetsi enyukireya, uye inogona kusanganiswa neU2O ceramics kuti ive mafuta enyukireya.
High-Giredhi Refractory - Special Metallurgical Crucible
BeO ceramic chigadzirwa chinhu chinoramba. BeO ceramic crucibles inogona kushandiswa kunyungudutsa isingawanzo uye yakakosha simbi, kunyanya panodiwa kuchena kwesimbi kana alloys. Iyo tembiricha yekushandisa ye crucible inogona kusvika 2000 ℃.
Nekuda kwekunyanya kunyunguduka kwayo (kunenge 2550 ° C), kugadzikana kwemakemikari kwakanyanya (alkali kuramba), kugadzikana kwekupisa uye kuchena, BeO ceramics inogona kushandiswa kunyungudutsa glazes uye plutonium. Pamusoro pezvo, macrucibles aya akashandiswa zvinobudirira kugadzira zviyero zvesirivha, goridhe uye platinamu. Iyo yepamusoro dhigirii ye "transparency" yeBeO kune electromagnetic mwaranzi inobvumira simbi sampuli kunyungudutswa nekudziisa induction.
Zvimwe Application
a. Beryllium oxide ceramics ine yakanaka thermal conductivity, iri maodha maviri ehukuru akakwira kupfuura anowanzo shandiswa quartz, saka laser ine hunyanzvi hwepamusoro uye hombe yekuburitsa simba.
b. BeO ceramics inogona kuwedzerwa sechikamu kune girazi remhando dzakasiyana siyana. Girazi rine beryllium oxide rinotumira X-rays. X-ray machubhu akagadzirwa negirazi iri anoshandiswa mukuongorora kwemaitiro uye mukurapa kurapa zvirwere zveganda.
Beryllium oxide ceramics uye mamwe maceramics emagetsi akasiyana, kusvika parizvino, yakakwira yekupisa conductivity uye yakaderera kurasikirwa maitiro zvakaoma kutsiviwa nezvimwe zvinhu.
