Alumina yumbu wani nau'i ne na kayan yumbu tare da alumina a matsayin babban jiki.Abubuwan yumbu na alumina suna da ingantacciyar haɓakawa, kayan injiniya, juriya da juriya mai tsayi, wanda kuma aka sani da tukwane na musamman.Al2O3 yumbu abu ne mai yawa hexagonal tsarin hada da oxygen ions, da aluminum ions cika a kashi biyu bisa uku na octahedral rata, wanda shi ne daidai da na halitta corundum barga α-Al2O3 tsarin, don haka yumbu yana da babban narkewa batu, high taurin, yana da kyau kwarai juriya.Alumina yumbu taurin ≥HRA85, taurin shine na biyu kawai zuwa lu'u-lu'u, juriyar sa yana da kyau sosai.
Gabaɗaya magana, alumina yumbu aluminum an raba shi zuwa nau'in gama gari da nau'in tsafta mai tsayi.Nau'in gama gari bisa ga abun ciki na Al2O3 an kasu kashi 92% alumina yumbu, 95% alumina yumbu, 96% alumina yumbu.High tsarki irin ne 99% alumina yumbu da kuma sama da yumbu, da sintering zafin jiki kamar yadda high as 1650-1990 ℃.99.7% -99.9% high tsarki alumina yumbu za a iya amfani da a cikin Electronics masana'antu a matsayin hadedde kewaye hukumar da high mita rufi kayan, semiconductor masana'antu a cikin nika silicon wafers, da dai sauransu, shi ne saffir da semiconductor silicon wafer sinadaran inji polishing key goyon bayan sassa. da abubuwan amfani.
Mafi girman abun ciki na alumina na yumbu masu tsayayya da lalacewa, mafi kwanciyar hankali aikin, wato, mafi girman abun ciki na aluminum, mafi kyawun aikin juriya.Alumina tukwane a matsayin ci-gaba yumbu abu, tare da saurin ci gaba na sababbin masana'antu kayan jurewa lalacewa, za a yi amfani da yadu a cikin zamani al'umma.
Chemshun Ceramics yana ba da nau'ikan yumbu masu tsafta iri-iri, kamar: 92% Al2O3 & 95% Al2O3 daidaitaccen lalacewa mai jurewa alumina yumbu liner, yumbu rufi guda da tabarma, hexagon / murabba'in yumbu tile, yumbu bututu / tube / gwiwar hannu, yumbu Silinda, yumbu block / cube, yumbu tubali, 99.7% alumina baseboard da alumina wafer polishing farantin, 99% alumina bulletproof yumbu, da dai sauransu.
