Nadiifinta sare ee LCD LED giraanta dahaarka dhoobada semiconductor

Alumina (Al2O3) isticmaalka ugu muhiimsan

Qaybaha qalabka wax soo saarka semiconductor (qaybaha godka, flanges dahaarka, qaybaha qalabka etching, xajin wafer);Qaybaha wax-soo-saarka (kala-soocida, mishiinka qulqulka hawada, mishiinka dhogorta);Qaybaha warshadaha guud (mashiinka wax-ka-qabashada laser-ka, shafka wareega, xajinta);Saxnaanta sare, saxnaanta, qalabka birta ah ee kuleylka u adkeysata (meelaynta meelaynta, qalabka shirarka);Xiro qaybo adkaysi u leh (hagaha mashiinka sawiridda fiilada, kanaalka siliga birta, tareenka hagaha);Qaybaha dahaarka korantada (insulators, gaskets, bushings).

Sifada

Alumina waa ceramics cad ama opalescent, iyadoo la isticmaalayo sifooyin koronto oo heer sare ah, horaantii bilaabay in loo isticmaalo qaybaha elektarooniga ah, isticmaalka ka badan, waa qalab aad u jaban ee ceramics sax ah.

Waxaan bixinaa badeecooyin nadiif ah oo sarreeya 99.5% iyo 99.9%.Nooca nadiifka sare ee alumina wuxuu leeyahay awood farsamo oo sarreeya, iska caabin daxalka aad u fiican, wuxuuna soo saari karaa alaabooyin waaweyn.

Intaa waxaa dheer, sababtoo ah caabbinta balaasmaha aadka u fiican, waxa kale oo loo isticmaali karaa qalabka CVD ama qaybaha qalabka etching.
