Ufa wa aluminium oxide wa Alpha-al2o3 99.99% Woyera
Ufa wa Alpha-alumina (α-Al2O3), womwe umadziwika kuti ufa wa aluminiyamu oxide, ndi chinthu chogwiritsidwa ntchito m'njira zosiyanasiyana chomwe chimagwiritsidwa ntchito m'mafakitale monga zadothi, zoyeretsera, zokometsera, zosakaniza, ndi zina zambiri. Nazi zina mwazofunikira za ufa wa alpha-Al2O3.
Kapangidwe ka Mankhwala:
Aluminium oxide (Al2O3): Kawirikawiri 99% kapena kupitirira apo.
Kukula kwa Tinthu:
Kugawa kwa tinthu tating'onoting'ono kumatha kusiyana malinga ndi zofunikira pakugwiritsa ntchito.
Kukula kwa tinthu tating'onoting'ono tingasiyane kuchokera ku sub-micron mpaka ma micron ochepa.
Ufa wa tinthu tating'onoting'ono tomwe timakhala ndi malo apamwamba komanso mphamvu yogwirira ntchito.
Mtundu:
Kawirikawiri ndi yoyera, yokhala ndi chiyero chapamwamba.
Kapangidwe ka Crystal:
Alpha-alumina (α-Al2O3) ili ndi kapangidwe ka kristalo ka hexagonal.
Malo Odziwika Pamwamba:
Kawirikawiri imakhala pakati pa 2 mpaka 20 m2/g.
Ufa wapamwamba pamwamba umapereka mphamvu yowonjezera komanso kuphimba pamwamba.
Chiyero:
Ufa wa alpha-Al2O3 woyera kwambiri umapezeka nthawi zambiri popanda kuipitsidwa kwambiri.
Mulingo wa chiyero nthawi zambiri umakhala 99% kapena kupitirira apo.
Kuchuluka kwa Zinthu:
Kuchuluka kwa ufa wa alpha-Al2O3 kumatha kusiyana kutengera njira yopangira kapena mtundu wake.
Kawirikawiri zimakhala pakati pa 0.5 ndi 1.2 g/cm3.
Kukhazikika kwa Kutentha:
Ufa wa Alpha-Al2O3 umakhala ndi kutentha kwabwino komanso kutentha kwambiri.
Malo osungunuka: Pafupifupi 2,072°C (3,762°F).
Kuuma:
Ufa wa Alpha-Al2O3 umadziwika ndi kuuma kwake kwakukulu.
Kulimba kwa Mohs: Pafupifupi 9.
Kusagwira Ntchito kwa Mankhwala:
Ufa wa Alpha-Al2O3 ndi wopanda mankhwala ndipo sugwirizana ndi mankhwala ambiri.
Ndi yolimba ku ma acid ndi alkali.
Ndikofunikira kudziwa kuti mafotokozedwe enieni a ufa wa alpha-Al2O3 amatha kusiyana pakati pa opanga ndi magulu enaake. Chifukwa chake, ndikofunikira kuyang'ana pa datasheet ya malonda kapena kufunsa wogulitsa kuti mudziwe zambiri komanso zofunikira zinazake pa ntchito yomwe mukufuna kugwiritsa ntchito.
1. Zipangizo zowala: phosphors zamtundu wa trichromatic zomwe zimagwiritsidwa ntchito ngati zinthu zazikulu zopangira phosphor yayitali, phosphor ya PDP, phosphor ya LED;
2. Zoumba zowonekera bwino: zimagwiritsidwa ntchito ngati machubu a fluorescent a nyali ya sodium yothamanga kwambiri, zenera lokumbukira lokha lokonzedwa ndi magetsi;
3. Kristalo imodzi: yopangira rubi, safiro, garnet ya aluminiyamu ya yttrium;
4. Chomera cha alumina champhamvu kwambiri: monga gawo lapansi lomwe limagwiritsidwa ntchito popanga ma circuits ophatikizika, zida zodulira ndi chowumitsira choyera kwambiri;
5. Wosakhazikika: amapanga chotsukira chagalasi, chitsulo, semiconductor ndi pulasitiki;
6. Diaphragm: Kugwiritsa ntchito popanga chophimba cholekanitsa batire ya lithiamu;
7. Zina: monga chophimba chogwira ntchito, zokometsera, zokometsera ndi zothandizira zokometsera, chophimba cha vacuum, zipangizo zapadera zagalasi, zipangizo zophatikizika, chodzaza utomoni, zodzoladzola za bio-ceramics ndi zina zotero.
