Alumina (al2O3)
Qeybaha saxda ah ee ay soo saartay kooxda waxsoosaarka caqliga leh ee Zhanghuri (Zhhimg) waxaa laga sameyn karaa ashyaa'da ceyriska ah ee 'zhanngghui'. Heerkulka dhaadheer oo kufilan iyo qaab sax ah, saxsanaanta cabbirka ah ee ± 0.001mm, sicirka ilaa Ra0.1, isticmaal heerkulka illaa 1600 digrii. Midabada kaladuwan ee dhoobada ah waxaa lagu sameyn karaa iyadoo loo eegayo shuruudaha macaamiisha, sida: madow, oks, casaan mugdi ah, oo loo isticmaali karo muddo dheer heerkul sare, vacuum iyo jawiga gaaska ee wasakhaysan.
Waxaa si weyn loogu isticmaalay qalab wax soo saar kala duwan oo Semiconductor ah: xirmooyin (choramic bracket), substrate (saldhigga), hubka / buundada (anipulaupator), qaybaha farsamada gacanta iyo hawada makaanikada.

Adeegsiga aluminina sareeya ee alumina:
1. Waxaa lagu dabaqay qalabka semiconductor: chopum chuck, goynta goynta, nadiifinta diskiga, choumikic chuck.
2. Qeybta Wareegga Wafluuqa
3. Wershadaha soo bandhiga ee loo yaqaan 'LED / LCD'
4. Xiriirka indhaha, warshadaha qoraxda: Tuubooyinka dhoobada, ulaha dhoobada ah, xargaha dhoobada, shaashadda ee shaashadda ee xayiraadda shaashadda.
5. Qeybaha kuleylka u adkaysta iyo korantada ee korantada: Hilaadda dhoobada.
Waqtigan xaadirka ah, dhoobada aluminium okide waxaa loo qaybin karaa daahir sare iyo dhoobada guud. Taxadda sare ee aluminium aluminium oksinium waxay tixraacaysaa walxaha dhoobada ka kooban in ka badan 99.9% al₂o₃. Sababta oo ah heerkulka uu ku gudajiray illaa 1650 - 1990 ° C iyo mawjaddeeda isbadalka ah ee 1 ~ 6μm, waxaa badanaa lagu sameeyaa shaashadda xargaha ah halkii ay noqon lahayd tuke-ka-soo-qaadida sodium ah oo ay ku jirto iftiinka iftiinka iyo iska caabbinta alkali. Warshadaha elektiroonigga ah, waxaa loo istcimaali karaa sida ugu soo noqnoqoshada-sare ee maaddada ku jirta substrates iC. Marka loo eego waxyaabaha kaladuwan ee aluminium oxide, taxanaha aluminium oxide ee caanka ah waxaa loo qaybin karaa dhoobada 99 dhoobada, 95 dhoobada ah, 90 dhoobada ah iyo 85 dhoobada. Mararka qaarkood, dhoobada leh 80% ama 75% ee aluminium oxide ayaa sidoo kale loo kala saaraa inuu yahay taxanaha aluminium ochisictic ee caadiga ah ee oxisum ochime. Waxaa ka mid ah, 99 aluminium okside walxaha dhoobada leh waxaa loo isticmaalaa in lagu soo saaro heerkul-sareeya oo ah tube-ka-daadashada iyo walxaha gaaska ah ee u adkaysiga leh, sida galka dhoobada dhoobada ah, taarikada dhoobada iyo taarikada tuubada. 95 Dhoobo aluminium ah ayaa inta badan loo isticmaalaa sidii xidhitaan iska caabin u adkaysta. Qulqulka 85 ee dhoobada ayaa badiyaa lagu qasaa sifooyinka qaarkood, sidaasna ay u hagaagto waxqabadka korantada iyo xoogga makaanikada. Waxay isticmaali kartaa molybdenum, nioiobium, Tantalum iyo shaabadaha kale ee birta ah, qaarna waxaa loo isticmaalaa sida aaladaha vacuum-ka korantada.
