Izici Ezibalulekile Ezithinta Ukuzinza Kwezinto Zobumba Ezingagugi

I-Alumina ceramics uhlobo lwezinto zobumba ezine-alumina njengomzimba oyinhloko. I-Alumina ceramics inomoya ongcono wokuqhuba, impahla yemishini, ukumelana nokuguguleka kanye nokumelana nokushisa okuphezulu, okwaziwa nangokuthi i-ceramics ekhethekile. Izinto zobumba ze-Al2O3 ziyisakhiwo esiqinile esinama-hexagonal esakhiwe ngama-ion e-oxygen, kanye nama-ion e-aluminium agcwele izingxenye ezimbili kwezintathu zegebe le-octahedral, elifana nesakhiwo se-α-Al2O3 esizinzile se-corundum yemvelo, ngakho-ke i-ceramic inendawo yokuncibilika ephezulu, ubunzima obuphezulu, futhi inokumelana okuhle kakhulu nokuguguleka. Ubulukhuni be-ceramic be-Alumina ≥HRA85, ubunzima bulandela idayimane kuphela, ukumelana kwabo nokuguguleka kuhle kakhulu.

Ngokuvamile, i-aluminium yobumba ye-alumina ihlukaniswe ngohlobo oluvamile nohlobo oluhlanzekile kakhulu. Uhlobo oluvamile ngokwe-Al2O3 luhlukaniswe ngo-92% we-alumina ceramic, 95% we-alumina ceramic, 96% we-alumina ceramic. Uhlobo oluhlanzekile kakhulu luyi-99% ye-alumina ceramic futhi ngaphezu kwe-ceramic, izinga lokushisa layo elishisayo lifinyelela ku-1650-1990℃. I-99.7%-99.9% ye-aluminium yobumba ehlanzekile kakhulu ingasetshenziswa embonini ye-elekthronikhi njengebhodi lesifunda elihlanganisiwe kanye nezinto zokufaka imvamisa ephezulu, imboni ye-semiconductor kuma-wafer e-silicon yokugaya, njll., iyi-sapphire kanye ne-semiconductor silicon wafer yamakhemikhali epholisha ngomshini izingxenye zokusekela kanye nezinto ezisetshenziswayo.

Uma okuqukethwe kwe-alumina kwe-ceramics ezimelana nokuguguleka kuphakeme, ukusebenza kuzinze kakhulu, okungukuthi, okuqukethwe kwe-aluminium kuphakeme, kulapho ukusebenza okumelana nokuguguleka kuba ngcono khona. I-Alumina ceramics njengezinto ze-ceramic ezithuthukisiwe, ngentuthuko esheshayo yezinto ezintsha ezimelana nokuguguleka zezimboni, izosetshenziswa kabanzi emphakathini wanamuhla.

I-Chemshun Ceramics inikeza izinhlobo ezahlukene ze-alumina ceramics ezihlanzekile kakhulu, njenge: 92% Al2O3 kanye 95% Al2O3 i-liner ceramic engagugi ejwayelekile, izingcezu ze-ceramic lining kanye nomata, ithayela le-ceramic le-hexagon/square, ipayipi/ithubhu/ingqiniba ye-ceramic, isilinda se-ceramic, ibhlogo/i-ceramic ceramic, isitini se-ceramic, ibhodi lesisekelo le-alumina elingu-99.7% kanye nepuleti lokupholisha le-alumina wafer, i-ceramic engangenisi izinhlamvu engu-99% ye-alumina, njll.
