Soo bandhigida aasaasiga ah ee aluminium nadiif ah oo sarreeya

Nadiifinta sare ee alumina waa kiimiko leh qaacidada kiimikaad ee Al2O3, oo nadiif ka ah in ka badan 99.99% waxaan u naqaannaa alumina nadiif ah oo sarreeya

macluumaadka lagama maarmaanka ah:

Qaaciddada molecular: Al2O3

Miisaanka molecular: 102

Barta dhalaalka: 2050 ℃

Cuf-jiidadka gaarka ah: Al2O3 α Nooca 2.5-3.95g/cm3

Qaabka crystal: γ Nooca α

Astaamaha: nadiifsanaan sare, cabbirka qayb ka mid ah waxaa lagu xakameyn karaa iyadoo loo eegayo habka, qaybinta cabbirka walxaha lebbiska ah, budo aan dhadhamin cad

falanqaynta kiimikada:

Nadiifinta sareeysa ee budada oksaydhka aluminium waa budo cad oo leh cabbir isku mid ah, kala firdhisan fudud, sifooyin kiimiko oo deggan, heerkul dhexdhexaad ah oo hoos u dhacaya iyo sifooyin wanaagsan;Beddelka sarreeya iyo ka kooban sodium hoose.Alaabtani waa alaabta ceeriin ee aasaasiga ah ee wax soo saarka kulaylka u adkaysta, xirashada iyo daxalka u adkaysta, sida aluminiumka sare ee refractories, alaabta dhoobada ee xoogga badan, dhinbiisha baabuurta, alaabta wax lagu shiido ee horumarsan iyo alaabooyin kale, oo leh tayo la isku halleyn karo. , barta dhalaalaysa sare, xasilloonida kulaylka wanaagsan, qallafsanaanta sare, caabbinta xirashada wanaagsan, xoogga farsamada sare, dahaarka koronto wanaagsan iyo iska caabin daxalka.Waxaa si weyn loo isticmaalaa in refractories qaabaysan iyo amorphous polishing muraayadda alaabta qurxinta sida binder kabka refractory, xidhashada abrasive qalab u adkaysta, fiber refractory-nadiifinta sare, ceramics gaar ah, dhoobada elektarooniga ah, ceramics qaab dhismeedka, birta ahama iyo granite.Waxay buuxin kartaa shuruudaha isticmaaleyaasha leh xaalado kala duwan oo isticmaalka iyo habka.Alumina-ku wuxuu qaataa aluminium warshadeed aasaasiga ah, aluminium hydroxide iyo tignoolajiyada wax lagu daro.Ka dib marka heerkulku hooseeyo calcination beddelka wejiga, waxa ay qabataa technology shiidi horumarsan iyo habka si ay u soo saaraan budada alumina firfircoon, taas oo lagu gartaa waxqabad weyn iyo size qayb ganaax.Waxay si gaar ah ugu habboon tahay badeecooyinka qaabaysan iyo refractories amorphous sida castables refractory, balaastikada, alaabta dayactirka, qalabka qoriga iyo alaabta daahan.Waxay door xoog leh ka ciyaartaa hagaajinta xoogga heerkulka sare iyo iska caabinta daxalka ee refractories

Codsiga ugu muhiimsan

1) Walxaha iftiinka: loo isticmaalo sida alaabta ceeriin ee ugu weyn ee fosfor trichromatic earth, fosfoor dheer ka dib, fosfoor PDP iyo fosfoor horseed u ah;

2) dhoobada hufan: loo isticmaalo sida tuubooyinka fluorescent ee nalalka sodium-cadaadiska sareeyo iyo daaqadaha xusuusta ee koronto ahaan loo akhriyi karo;

3) Hal crystal: loo isticmaalo wax soo saarka Ruby, sapphire iyo yttrium aluminium garnet;

4) Xoog sare iyo ceramics aluminium sare: loo isticmaalo in lagu soo saaro substrates wareeg ah isku dhafan, qalab goynta iyo crucibles-nadiifinta sare;

5) Abrasive: abrasive loo isticmaalo wax soo saarka galaas, biraha, semiconductor iyo caag;

6) Diaphragm: loo isticmaalo wax soo saarka daahan diaphragm batari lithium;

7) Kuwa kale: loo isticmaalo sida daahan firfircoon, adsorbent, kicinta iyo qaadaha qaadaha, daahan vacuum, alaabta ceeriin gaar ah galaas, composites, resin filler, bioceramics, iwm
