Badeecadaha
Budada Alumina ee lagu nadiifiyo
Budada Alumina waa mid ku habboon wax soo saarka aluminiumka iyo kuwa kale ee u baahan adkeysi iyo iska caabin xoqidda ama noocyada kale ee xirashada kiimikada. Budada Alumina sidoo kale waxay ku habboon tahay alaabada u baahan daxalka iyo iska caabinta xirashada, iyo alaabada u baahan kuleyl sare, sida codsiyada dahaarka korontada iyo kuleylka.
Waxqabadka badeecada:
Badeecadu waa budo cad ama ciid fiican waxayna leedahay firfircooni sintering oo wanaagsan. Kuma milmo biyaha, kuma milmo aashito iyo xal alkali ah. Cabbirka walxaha protocrystal waa la xakamayn karaa.

Astaamaha Budada Alumina:
1. Iska caabbinta kiimikada
2. Alumina saafi ah oo sareysa, alumina oo ka badan 99%
3. Iska caabin heerkul sare, heerkulka shaqadu waa 1600 ℃, ilaa 1800 ℃
4. iska caabbinta shoogga kulaylka, deggan oo adag in la jabiyo
5. Qaabaynta iyadoo la isticmaalayo shubid, waxay leedahay cufnaan sare
Budada Alumina waxay leedahay faa'iidooyinka daahirnimada sare iyo cufnaanta sare, oo inta badan loo isticmaalo dhoobada, galaaska, balaastikada, dharka, qalabka dhismaha, xoqidda, warqadda iyo daawada, iyo meelo kale oo badan.
Faa'iidada Budada Alumina:
1. Iyada oo loo marayo warshadda hawada iyo kala-soocidda shan lakab, qaybinta cabbirka hadhuudhka waa cidhiidhi, waxtarka shiididdu waa sarreeyaa, saamaynta dhalaalintu waa wanaagsan tahay, hufnaanta shiididdu aad bay uga sarreysaa xoqidda jilicsan sida silica.
2. Muuqaal wanaagsan oo walxaha ah, dusha sare ee shayga la safaynayo wuxuu leeyahay heer sare oo siman, habka ugu dambeeya ee nadiifinta fiican, saameynta shiididda iyo nadiifinta ayaa ka wanaagsan budada cad ee corundum.
1. Nadiifinta shaashadda taleefanka, oo ay ku jiraan nadiifinta kama dambaysta ah ee shaashadda taleefanka gacanta ee safayr, shaashadda muraayadda taleefanka gacanta. Waxa kale oo loo isticmaali karaa: dhagaxyada macmal ah, zircon, galaas heer sare ah, dhagaxyo dabiici ah, jadeecada, agate iyo dhammaystir kale oo gariir leh (nadiifinta mashiinka, nadiifinta duubista), nadiifinta gacanta (nadiifinta shiididda) iwm.
2. Nadiifinta birta, oo ay ku jiraan qolofka taleefanka gacanta, giraangiraha gaariga, nadiifinta qalabka heer sare ah.
3. Si ballaaran ayaa loogu isticmaalaa shiidida iyo nadiifinta semiconductors, kiristaalka, aluminiumka, birta, birta aan daxalka lahayn, dhagaxa, galaaska, iwm.
4. Gaar ahaan ku habboon shiididda iyo dhalaalinta saameynta muraayadda ee birta aan miridhku lahayn, naxaasta, agabka kale ee birta ah, iyo warshadaha galaaska.
