Alpha-al2o3 Aluminium oxide ufa 99.99% Chiyero
Alpha-alumina (α-Al2O3) ufa, womwe umadziwika kuti aluminium oxide powder, ndi zinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito m'mafakitale monga ceramics, refractories, abrasives, catalysts, ndi zina.Nazi zina zodziwika bwino za alpha-Al2O3 ufa
Mapangidwe a Chemical:
Aluminium oxide (Al2O3): Nthawi zambiri 99% kapena kupitilira apo.
Kukula kwa Tinthu:
Kugawa kwa tinthu ting'onoting'ono kumatha kusiyanasiyana kutengera zomwe mukufuna.
Kukula kwa tinthu ting'onoting'ono kumatha kuchoka ku submicron mpaka ma microns angapo.
Finer tinthu kukula ufa kupereka apamwamba pamwamba ndi reactivity.
Mtundu:
Childs woyera, ndi mkulu mlingo wa chiyero.
Kapangidwe ka Crystal:
Alpha-alumina (α-Al2O3) ili ndi mawonekedwe a kristalo a hexagonal.
Malo Enieni Pamwamba:
Kawirikawiri mumtundu wa 2 mpaka 20 m2 / g.
Ufa wapamwamba wa pamwamba umapereka kuwonjezereka kwa reactivity ndi kuphimba pamwamba.
Chiyero:
Mafuta apamwamba a alpha-Al2O3 amapezeka kawirikawiri ndi zosafunika zochepa.
Mulingo wachiyero nthawi zambiri ndi 99% kapena kupitilira apo.
Kuchulukana Kwambiri:
Kuchulukirachulukira kwa alpha-Al2O3 ufa kumatha kusiyanasiyana malinga ndi njira yopangira kapena giredi.
Nthawi zambiri amachokera ku 0.5 mpaka 1.2 g/cm3.
Thermal Kukhazikika:
Alpha-Al2O3 ufa amawonetsa kukhazikika kwamafuta komanso malo osungunuka kwambiri.
Posungunuka: Pafupifupi 2,072°C (3,762°F).
Kulimba:
Alpha-Al2O3 ufa amadziwika chifukwa cha kuuma kwake kwakukulu.
Kuuma kwa Mohs: Pafupifupi 9.
Chemical Inertness:
Alpha-Al2O3 ufa ndi inert mankhwala ndipo sagwirizana ndi mankhwala ambiri.
Imalimbana ndi zidulo ndi ma alkalis.
Ndikofunika kuzindikira kuti ndondomeko yeniyeni ya alpha-Al2O3 ufa imatha kusiyana pakati pa opanga ndi magiredi enieni.Chifukwa chake, ndikofunikira kuyang'ana pazomwe mukugulitsazo kapena kufunsira kwa omwe akukupatsani kuti mumve zambiri komanso zofunikira pazomwe mukufuna.
1.Luminescent zipangizo: osowa lapansi trichromatic phosphors ntchito ngati zazikulu zopangira yaitali afterglow phosphor, PDP phosphor, LED phosphor;
2.Transparent Ceramics: amagwiritsidwa ntchito ngati machubu a fulorosenti a nyali ya sodium yapamwamba, zenera la kukumbukira lokhazikika pamagetsi;
3.Single Crystal: kupanga ruby, safiro, yttrium aluminium garnet;
4.Mkulu wamphamvu alumina ceramic: monga gawo lapansi lomwe limagwiritsidwa ntchito popanga mabwalo ophatikizika, zida zodulira ndi crucible yoyera;
5.Abrasive:kupanga abrasive wa galasi, zitsulo, semiconductor ndi pulasitiki;
6.Diphragm: Ntchito yopangira zokutira zolekanitsa za batri ya lithiamu;
7.Zina: monga zokutira yogwira, adsorbents, chothandizira ndi chothandizira zothandizira, vacuum ❖ kuyanika, magalasi apadera zipangizo, kompositi zipangizo, utomoni filler, bio-ceramics etc.
