Isitena somlilo se-alumina luhlobo olutsha lobushushu obuphezulu bezinto zokufudumeza kwaye zenziwe nge-alumina yeshishini kwiziko lombane ngokunyibilikisa nokuvuthela. I-alumina bubble refractory ifomu yekristale yezitena yi-Al2O3 microcrystal kunye nomzimba oyintloko yi-alumina bubble enokwenziwa ukuba ibe zizo zonke iintlobo zeemveliso ezinemilo eyahlukeneyo yokukhonza ubushushu obuphezulu be-1800 ℃ kunye namandla omatshini aphezulu kunye nobuninzi obuphantsi.
I-aluminiyam bubblle firebrick ithatha i-alumina bubble ibhola njengeyona nto iphambili yemathiriyeli ekrwada, ukusebenza okuphezulu komgubo we-ultrafine njenge-annexing agent kunye ne-organic substance njenge-agent ebophelelayo ngokubumba kunye nokomisa, kwaye emva koko igxothwe kwi-shuttle kiln yokushisa okuphezulu.
Izitena zomlilo ze-Aluminium bubblle zineempawu zokufudumeza ukushisa kunye ne-conductivity ephantsi ye-thermal, enokubangela umphumo omkhulu wokushisa ukushisa, ukunciphisa inkunkuma yokushisa kunye nokuphucula ukusebenza kakuhle kwe-thermal. usebenzisa isitena esinqandayo se-aluminiyam kunokonga amandla ukuya kuma kwi-30%. kunye nobushushu benkonzo ye-alumina bubble block' buphezulu ukuya kuthi ga kwi-1750 ℃. Uzinzo lwe-thermal lulungile kwaye izinga lokutshintsha komgca wokufudumeza liphantsi, ibhloko ye-aluminium bubble ingabangela ubomi obude benkonzo.

Isitena se-alumina bubble luhlobo lwezinto ezinqabileyo ezibaluleke kakhulu zokuxhathisa ubushushu obuphezulu kunye neemfuno ezikhethekileyo zezikhundla zeziko kunye neziko, ezisetyenziswa kakhulu njengezitena zokukhusela izitena zokugquma iziko kunye neziko, kunye nezitena ze-aluminiyam zingasetyenziselwa inkonzo. iilinings ekuveliseni iquartz yococeko oluphezulu kushishino lwe-electronics ezifana ne-ceramic tile linings kwii-iturbines zegesi kunye ne-back linings kwi-reactors.
Umzi-mveliso we-RS refractory njengomenzi wezitena ze-alumina bubble e-china, uneenzuzo ezininzi zokukhuphisana kwimarike. ukuba unemfuno yezitena ze-aluminium bubble, okanye unemibuzo malunga ne-aluminium bubble firebrick malunga nezibonakaliso ezibonakalayo kunye neekhemikhali, nceda uqhagamshelane nathi simahla, siya kukubonelela ngezitena eziphezulu ze-aluminium bubble refractory.
