Ngalo lonke ixesha xa sithetha nge-beryllium oxide, impendulo yokuqala kukuba inetyhefu nokuba yeyabantu abangengabo abanamava okanye iingcali. Nangona i-beryllium oxide inetyhefu, iiseramikhi ze-beryllium oxide azinabungozi.
I-Beryllium oxide isetyenziswa kakhulu kwiinkalo ze-metallurgy ekhethekileyo, iteknoloji ye-vacuum electronic, iteknoloji yenyukliya, i-microelectronics kunye neteknoloji ye-photoelectron ngenxa yokuqhuba kwayo okuphezulu kobushushu, ubushushu obuphezulu, i-dielectric constant ephantsi, ilahleko ephantsi ephakathi, kunye nokuguquguquka okuhle kwenkqubo.
Izixhobo ze-elektroniki ezinamandla aphezulu kunye neesekethe ezidibeneyo
Ngaphambili, uphando nophuhliso lwezixhobo ze-elektroniki belugxile kakhulu kuyilo lokusebenza kunye noyilo lweendlela, kodwa ngoku ingqalelo engakumbi inikwa kuyilo lobushushu, kwaye iingxaki zobugcisa zokulahleka kobushushu kwezixhobo ezininzi ezinamandla aphezulu azisonjululwanga kakuhle. I-beryllium oxide (BeO) sisixhobo se-ceramic esine-conductivity ephezulu kunye ne-dielectric constant ephantsi, nto leyo eyenza ukuba isetyenziswe kakhulu kwicandelo lobuchwepheshe be-elektroniki.
Okwangoku, ii-ceramics ze-BeO zisetyenziswa ekupakisheni ii-microwave ezinamandla aphezulu, ekupakisheni ii-transistor ze-elektroniki ezisebenza rhoqo, kunye nee-multichip ezininzi ezinoxinano oluphezulu, kwaye ubushushu obuveliswa kwinkqubo bunokuchithwa ngexesha elifanelekileyo ngokusebenzisa izixhobo ze-BeO ukuqinisekisa uzinzo kunye nokuthembeka kwenkqubo.
Isixhobo sokusabela senyukliya
Izinto zeseramikhi zezinye zezona zinto zibalulekileyo ezisetyenziswa kwi-reactor yenyukliya. Kwii-reactors nakwii-converters, izinto zeseramikhi zifumana imitha evela kumasuntswana anamandla aphezulu kunye ne-beta rays. Ke ngoko, ukongeza kubushushu obuphezulu kunye nokumelana nokugqwala, izinto zeseramikhi nazo kufuneka zibe nokuzinza okungcono kwesakhiwo. Ukubonakaliswa kwe-neutron kunye ne-moderate ye-nuclear fuel zihlala zenziwe nge-BeO, B4C okanye i-graphite.
Ukuzinza kwemitha yobushushu obuphezulu kweeseramiki ze-beryllium oxide kubhetele kunesinyithi; uxinano luphezulu kunesinyithi se-beryllium; amandla angcono xa kushushu kakhulu; ukuhanjiswa kobushushu kuphezulu kwaye ixabiso liphantsi kunesinyithi se-beryllium. Zonke ezi mpawu zibalaseleyo zenza ukuba ifaneleke ngakumbi ukusetyenziswa njenge-reflector, i-moderator, kunye ne-dispersed phase combustion collective kwii-reactors. I-Beryllium oxide ingasetyenziswa njengeentonga zokulawula kwii-reactors zenyukliya, kwaye ingasetyenziswa kunye ne-U2O ceramics njenge-nuclear fuel.
Isiqwenga esikhethekileyo sesinyithi
Enyanisweni, ii-ceramics ze-BeO zizinto ezichaseneyo. Ukongeza, i-ceramic crucible ye-BeO ingasetyenziswa ekunyibilikeni kweentsimbi ezinqabileyo kunye neentsimbi ezixabisekileyo, ingakumbi kwisinyithi okanye i-alloy ecocekileyo kakhulu, kunye nobushushu bokusebenza be-crucible obufikelela kwi-2000 ℃. Ngenxa yobushushu bazo obuphezulu bokunyibilika (2550 ℃) kunye nozinzo oluphezulu lweekhemikhali (i-alkali), uzinzo lobushushu kunye nobunyulu, ii-ceramics ze-BeO zingasetyenziselwa i-glaze enyibilikisiweyo kunye ne-plutonium.
Ezinye izicelo
Iiseramiki zeBeryllium oxide zine-thermal conductivity elungileyo, ephindwe kabini ngobukhulu kune-quartz eqhelekileyo, ngoko ke i-laser inamandla aphezulu okukhupha.
Iiseramikhi zeBeO zingongezwa njengenxalenye yezinto ezahlukeneyo zeglasi. Iglasi equlethe i-beryllium oxide, enokudlula kwii-x-ray, isetyenziselwa ukwenza iityhubhu ze-X-ray ezinokusetyenziselwa uhlalutyo lwesakhiwo kunye nokunyanga izifo zesikhumba.
Iiseramikhi zeBeryllium oxide zahlukile kwezinye iiseramikhi ze-elektroniki. Okwangoku, ukuhanjiswa kwayo kobushushu obuphezulu kunye neempawu zayo zokulahleka okuphantsi kunzima ukuzitshintsha zezinye izinto. Ngenxa yemfuno ephezulu kwiinkalo ezininzi zesayensi kunye nezobuchwepheshe, kunye nobuthi be-beryllium oxide, amanyathelo okukhusela angqongqo kwaye anzima, kwaye zimbalwa iifektri emhlabeni ezinokwenza iiseramikhi zeBeryllium oxide ngokukhuselekileyo.
