I-Beryllium oxide ceramics ene-conductivity ephezulu ye-thermal kunye neempawu ezilahlekileyo eziphantsi
Iiseramikhi ze-BeO okwangoku zisetyenziswa ekusebenzeni okuphezulu, iipakethe zemicrowave ezinamandla aphezulu, iipakethe ze-electronic transistor ezisebenza ngamaza amaninzi, kunye noxinaniso oluphezulu lwecandelo le-chips ezininzi. Ukusetyenziswa kwezinto ze-BeO kunokusasaza ukushisa okwenziwa kwinkqubo ngexesha lokuqinisekisa ukuzinza nokuthembeka kwenkqubo.
I-BeO isetyenziselwa ukupakishwa kwe-transistor ye-elektroniki ye-high-frequency
Qaphela: I-Transistor sisixhobo esiqinileyo se-semiconductor, ngokufumanisa, ukulungiswa, ukukhulisa, ukutshintsha, ukulawulwa kwamandla ombane, ukumodareyitha kwesignali kunye neminye imisebenzi. Njengohlobo lokutshintsha kwangoku, i-transistor inokulawula imveliso yangoku ngokusekwe kwi-voltage yegalelo. Ngokungafaniyo nokutshintsha oomatshini abaqhelekileyo, ii-transistors zisebenzisa unxibelelwano lwe-telecommunications ukulawula ukuvulwa nokuvalwa kwazo, kwaye isantya sokutshintsha sinokukhawuleza kakhulu, kwaye isantya sokutshintsha elabhoratri sinokufikelela ngaphezulu kwe-100GHz.
Ukusetyenziswa kwezixhobo zeNyukliya
Isixhobo se-nyukliya se-ceramic ye-ceramic sesinye sezinto ezibalulekileyo ezisetyenziswa kwi-reactors, kwi-reactors kunye ne-fusion reactors, izinto ze-ceramic zifumana amasuntswana anamandla aphezulu kunye nemitha ye-gamma, ke ngoko, ukongeza kubushushu obuphezulu, ukumelana nokugqwala, izixhobo ze-ceramic nazo kufuneka zibe nokulungileyo. uzinzo lwesakhiwo. Izibonisi zeneutron kunye neemodareyitha (iimodareyitha) zamafutha enyukliya zidla ngokuba yi-BeO, B4C okanye imathiriyeli yegraphite.
I-Beryllium oxide ceramics inozinzo olungcono lobushushu bokukhanya kwe-irradiation kunesinyithi, ubuninzi obuphezulu kunentsimbi ye-beryllium, amandla angcono kwiqondo lokushisa eliphezulu, ukuhanjiswa kwe-thermal ephezulu, kunye nexabiso eliphantsi kune-beryllium metal. Ikwalungele ukusetyenziswa njengesibonisi, imodareyitha kunye neqela lesigaba sokusasazwa kokutsha kwi-reactor. I-Beryllium oxide ingasetyenziswa njengentonga yokulawula kwiireactors zenyukliya, kwaye inokudityaniswa neeseramics ze-U2O ukuze ibe sisibaso senyukliya.
I-High-Grade Refractory-I-Special Metallurgical Crucible
Imveliso ye-BeO ceramic yinto enqabileyo. I-BeO ye-ceramic crucibles ingasetyenziselwa ukunyibilikisa isinyithi esinqabileyo kunye nexabiso, ngakumbi apho kufuneka iintsimbi ezicocekileyo okanye i-alloys. Ubushushu obusebenzayo be-crucible bunokufikelela kwi-2000 ℃.
Ngenxa yobushushu obunyibilikayo obuphezulu (malunga ne-2550 ° C), ukuzinza kweekhemikhali eziphezulu (ukuxhathisa kwe-alkali), ukuzinza kwe-thermal kunye nokucoceka, ii-ceramics ze-BeO zingasetyenziselwa ukunyibilikisa i-glaze kunye ne-plutonium. Ukongeza, ezi crucibles zisetyenziswe ngempumelelo ukuvelisa iisampuli eziqhelekileyo zesilivere, igolide kunye neplatinam. Iqondo eliphezulu "lokungafihli" kwe-BeO ukuya kwimitha ye-electromagnetic ivumela iisampulu zesinyithi ukuba zinyibilike ngokufudumeza kwe-induction.
Olunye usetyenziso
a. I-Beryllium oxide ceramics ine-conductivity efanelekileyo ye-thermal, eyi-odolo ezimbini zobukhulu obuphezulu kune-quartz eqhelekileyo, ngoko i-laser inokusebenza okuphezulu kunye negunya elikhulu lokuphuma.
b. Iikeramics ze-BeO zingongezwa njengenxalenye yeglasi yeengoma ezahlukeneyo. Iglasi eneberyllium oxide ehambisa iiX-reyi. Iityhubhu ze-X-ray ezenziwe ngale glasi zisetyenziselwa uhlalutyo lwesakhiwo kunye namayeza ukunyanga izifo zesikhumba.
I-Beryllium oxide ceramics kunye nezinye iiseramics ze-elektroniki zahlukile, ukuza kuthi ga ngoku, ukuhanjiswa kwayo okuphezulu kwe-thermal kunye neempawu ezilahlekileyo eziphantsi kunzima ukutshintshwa nezinye izinto.
