Aikace -aikace na babban tsarki alumina yumbu:
1. Ana amfani da kayan aikin semiconductor: yumbu injin cuku, yanke diski, tsabtace diski, yumbu CHUCK.
2. Wafer canja sassa: wafer handling chucks, wafer yankan fayafai, wafer discs discs, wafer optical dubawa tsotse kofuna.
3. LED / LCD flat panel nuni masana'antu: yumbu bututun ƙarfe, yumbu niƙa diski, LIFT PIN, PIN dogo.
4. Sadarwar gani, masana'antar hasken rana: bututun yumbu, sandunan yumbu, allon allon allon buga yumbu scrapers.
5. Zazzabi mai jurewa da sassauƙan wutar lantarki: ɗaukar yumbu.
A halin yanzu, aluminium oxide yumbu za a iya raba shi zuwa babban tsarkin da yumbu na gama gari. Babban tsarkin aluminium oxide ceramics yana nufin kayan yumbu wanda ya ƙunshi sama da 99.9% Al₂O₃. Saboda zafin zafinsa na har zuwa 1650 - 1990 ° C da raƙuman watsawar sa na 1 ~ 6μm, galibi ana sarrafa shi zuwa gilashin da aka haɗa maimakon platinum giciye: wanda za'a iya amfani dashi azaman bututun sodium saboda hasken watsawa da juriya na lalata karfe alkali. A cikin masana'antar lantarki, ana iya amfani da ita azaman babban abin rufewa don abubuwan IC. Dangane da abubuwan ciki daban -daban na oxide na aluminium, ana iya raba jerin yumɓin oxide na aluminium a cikin yumbu 99, yumbu 95, tukwane 90 da tukwane 85. Wani lokaci, yumbu tare da 80% ko 75% na aluminum oxide kuma ana rarrabasu azaman jerin yumbu na oxide na aluminium. Daga cikin su, ana amfani da kayan yumɓu na oxide 99 don samar da ƙwanƙolin zafi mai zafi, bututu mai murƙushe wuta da kayan da ba za a iya jurewa ba, kamar ɗaukar yumbu, hatimin yumbu da faranti na bawul. 95 aluminum ceramics galibi ana amfani da shi azaman sashin tsayayya da lalacewa. 85 galibi ana cakuda yumɓu a wasu kaddarorin, ta hakan yana haɓaka aikin lantarki da ƙarfin injin. Yana iya amfani da molybdenum, niobium, tantalum da sauran hatimin ƙarfe, kuma wasu ana amfani da su azaman na'urorin injin lantarki.
