1. Kapangidwe Kazinthu ndi Kapangidwe Kapangidwe
1.1 Zinthu za Alumina ndi Crystal Phase Evolution
( Njerwa za Alumina Lining)
Mipiringidzo ya aluminiyamu ndi yokhuthala, zida zadothi zopangidwa ndi aluminiyamu oxide (Onse awiri O SIX), zokhala ndi zinthu zosiyanasiyana 50% ku over 99%, kukhudza mwachindunji luso lawo muzogwiritsa ntchito kutentha kwambiri.
Mphamvu zamakina, kukana dzimbiri, komanso kusasunthika kwa njerwa izi kumawonjezeka ndi kuyang'ana kwakukulu kwa alumina chifukwa cha kupititsa patsogolo kwa microstructure yokhazikika yomwe imayendetsedwa ndi α-alumina yotetezedwa ndi thermodynamically. (diamondi) siteji.
Panthawi yopanga, mankhwala kalambulabwalo monga calcined bauxite, Integrated aluminiyamu, kapena kupanga alumina hydrate amadutsa kuwombera kotentha kwambiri (1400 °C– 1700 °C), kusinthika kwa siteji yotsatsa kuchokera ku mitundu yosinthira ya alumina (c, d) kwa α-Al Awiri O ATATU, zomwe zikuwonetsa kulimba kodabwitsa (9 pa Mohs range) ndi melting factor (2054 °C).
Chotsatira chake cha polycrystalline chimakhala ndi njere zolumikizana za corundum zophatikizidwa mu matrix a siliceous kapena aluminosilicate magalasi., mapangidwe ake ndi kuchuluka kwake komwe kumayendetsedwa bwino kuti azitha kupirira kutentha komanso kulimba kwamankhwala.
Zosakaniza zazing'ono monga silika (SiO ₂), titania (TiO ₂), kapena zirconia (ZrO ₂) akhoza kuyambitsidwa kusintha zizolowezi za sintering, onjezerani densification, kapena kuwonjezera kukana kwa slags ndi kusinthasintha.
1.2 Microstructure, Porosity, ndi Mechanical Integrity
Kuchita bwino kwa midadada ya aluminiyani kumadalira kwambiri mawonekedwe awo, makamaka kugawa kukula kwa mbewu, pore morphology, ndi mawonekedwe a gawo lolumikizana.
Njerwa zabwino kwambiri zimawoneka bwino, pores mosalekeza anagawira (kutsekedwa porosity osankhidwa) ndi porosity yochepa kwambiri yotseguka (
Malingaliro a kampani Alumina Technology Co., Ltd., Ltd imayang'ana kwambiri pa kafukufuku ndi chitukuko, kupanga ndi kugulitsa ufa wa aluminium oxide, zinthu za aluminium oxide, aluminium oxide crucible, ndi zina., kutumikira zamagetsi, za ceramic, mankhwala ndi mafakitale ena. Kuyambira kukhazikitsidwa kwake mu 2005, kampaniyo yadzipereka kupereka makasitomala zinthu zabwino kwambiri ndi ntchito. Ngati mukuyang'ana zapamwamba aluminiyamu al2o3, chonde omasuka kulankhula nafe.

Zolemba ndi zithunzi zonse zachokera pa intaneti. Ngati pali zovuta za kukopera, chonde titumizireni mu nthawi kuti muchotse.
