Njerwa yamoto ya aluminiyamu yopepuka yopepuka

Njerwa za buluu za alumini ndi mtundu wa zida zopulumutsa mphamvu kwambiri komanso kutentha kwambiri. Alumina bubble mpira ndi mtundu watsopano wazinthu zotenthetsera zotentha kwambiri. Amapangidwa ndi aluminiyamu yamafakitale posungunuka ndi kuwomba mu ng'anjo yamagetsi, ndipo mawonekedwe a kristalo ndi a-Al2O3 microcrystals. Ndi mipira ya aluminiyamu ngati thupi lalikulu, zopangira zamitundu yosiyanasiyana zimatha kupangidwa, ndi kutentha kwambiri kwa 1800 ℃. Zogulitsazo zimakhala ndi mphamvu zamakina apamwamba, zomwe zimachulukitsa kangapo kuposa zazinthu zopepuka, ndipo kuchuluka kwa voliyumu ndi theka la zinthu za corundum. Zakhala zikugwiritsidwa ntchito kwambiri m'malo otentha kwambiri komanso otentha kwambiri monga ng'anjo zamafuta a petrochemical gasification, makina opangira kaboni wakuda mafakitale, ndi ng'anjo zopangira zitsulo zamakampani, ndipo zapeza zotsatira zogwira mtima kwambiri zopulumutsa mphamvu.
