Kuyambitsa koyambirira kwa alumina yoyera kwambiri

High chiyero alumina ndi mankhwala okhala ndi chilinganizo chamankhwala cha Al2O3, chokhala ndi chiyero choposa 99.99% chomwe timachidziwa ngati alumina yoyera kwambiri.

mfundo zofunika:

Molecular formula: Al2O3

Kulemera kwa mamolekyu: 102

Malo osungunuka: 2050 ℃

Kukoka kwapadera: Al2O3 α Mtundu wa 2.5-3.95g/cm3

Mawonekedwe a kristalo: γ Mtundu α mtundu

Features: mkulu chiyero, tinthu kukula akhoza lizilamuliridwa molingana ndi ndondomeko, yunifolomu tinthu kukula kugawa, woyera ufa wopanda pake

Chemical Analysis:

High chiyero zotayidwa okusayidi ufa ndi ufa woyera ndi yunifolomu tinthu kukula, mosavuta kubalalitsidwa, khola mankhwala katundu, zolimbitsa kutentha shrinkage ndi katundu sintering;Kutembenuka kwakukulu komanso kutsika kwa sodium.Izi ndizopangira zopangira zopangira zinthu zosagwira kutentha, zosavala komanso zosagwira dzimbiri, monga ma aluminium refractories apamwamba, zida za ceramic zolimba kwambiri, ma spark plugs amagalimoto, zida zapamwamba zogaya ndi zinthu zina, zodalirika. , malo osungunuka kwambiri, kukhazikika kwabwino kwa kutentha, kuuma kwakukulu, kukana kuvala bwino, mphamvu zamakina apamwamba, kutsekemera kwabwino kwa magetsi ndi kukana kwa dzimbiri.Amagwiritsidwa ntchito kwambiri mu mawonekedwe owoneka bwino komanso amorphous refractories Galasi kupukuta kwa zinthu zokongoletsera monga refractory castable binder, zida zosagwira abrasive, ulusi wonyezimira wapamwamba, zoumba zapadera, zoumba zamagetsi, zoumba, zitsulo zosapanga dzimbiri ndi granite.Ikhoza kukwaniritsa zofunikira za ogwiritsa ntchito osiyanasiyana ndi zochitika za ndondomeko.Aluminium imatenga aluminiyamu yamafakitale, aluminiyamu hydroxide ndi ukadaulo wowonjezera.Pambuyo otsika-kutentha gawo kutembenuka calcination, izo utenga patsogolo luso akupera ndi ndondomeko kubala adamulowetsa aluminiyamu ufa, amene amakhala ndi ntchito yaikulu ndi kukula bwino tinthu.Ndizoyenera kwambiri pazinthu zowoneka bwino komanso ma amorphous refractories monga ma refractory castables, pulasitiki, zida zokonzera, zida zowombera mfuti ndi zida zokutira.Imathandiza kwambiri pakuwongolera mphamvu ya kutentha kwambiri komanso kukana kwa dzimbiri kwa ma refractories

Ntchito yayikulu

1) Luminescent zakuthupi: zogwiritsidwa ntchito ngati zopangira zazikulu zapadziko lapansi trichromatic phosphor, long afterglow phosphor, PDP phosphor ndi led phosphor;

2) Zoumba zowoneka bwino: zogwiritsidwa ntchito ngati machubu a fulorosenti a nyali zolimba kwambiri za sodium ndi mazenera owerengera owerengeka okha;

3） Krustalo imodzi: yogwiritsidwa ntchito popanga ruby, safiro ndi yttrium aluminium garnet;

4) Mphamvu zazikulu ndi zoumba za aluminiyamu: zomwe zimagwiritsidwa ntchito popanga magawo ophatikizika ozungulira, zida zodulira ndi zitsulo zoyera kwambiri;

5) Abrasive: abrasive ntchito kupanga galasi, zitsulo, semiconductor ndi pulasitiki;

6) Diaphragm: yogwiritsidwa ntchito popanga zokutira za diaphragm za batri ya lithiamu;

7) Ena: amagwiritsidwa ntchito ngati zokutira yogwira, adsorbent, chothandizira ndi chonyamulira chonyamulira, zingalowe ❖ kuya, galasi zipangizo wapadera, nsanganizo, utomoni filler, bioceramics, etc.
