I-alumina silica isitena somlilo luhlobo lwe-alumina silica refractory materials, i-alumina silicate isitena se-refractory sineempawu zokuchasana okuphezulu, ukuxhathisa okulungileyo kunye namandla aphezulu. Isitena se-aluminium silicate refractory sibandakanya iintlobo ezininzi zezitena zomlilo ezifana nezitena ze-silica, izitena ze-fireclay, izitena eziphezulu ze-alumina, izitena ze-mullite kunye ne-corundum Brick. Isitena somlilo se-alumina silica singasetyenziselwa zonke iintlobo zezixhobo ezishushu.
Ngokomyalelo wokunyuka komxholo ukusuka kwi-SiO2 ukuya kwi-Al2O3, izitena zomlilo ze-aluminium ze-aluminium zihlelwa kwezi ndidi zilandelayo.
Isitena se-silica: umxholo we-SiO2 mkhulu kune-93%,
Izitena zodongwe: umxholo we-Al2O3 ngu-30% -48%,
Izitena eziphezulu ze-alumina: umxholo we-Al2O3 mkhulu kune-48%,
Isitena se-Mullite: umxholo we-Al2O3 mkhulu okanye ulingana no-72%, kwaye umxholo we-SiO2 mkhulu okanye ulingana no-28%,
Isitena se-Corundum: umxholo we-Al2O3 ungaphezulu kwe-90%.
Izitena ze-silica zisetyenziselwa ukwakha i-oven ye-coke, i-oven yeglasi, i-ceramic kiln, i-carbon calcinations furnace kwaye ayifanelekanga ukusetyenziswa kwizixhobo zokufudumeza kunye nokuguquguquka kweqondo lokushisa phantsi kwe-600 ℃.
Izitena zodongwe zisoloko zisetyenziswa kwiziko eliqhumayo, isifudumezi-siqhumiso esishushu, kwiziko lokufudumeza, ibhoyila yamandla, i-lime kiln, i-rotary kiln, i-ceramic kiln kunye ne-calcining kiln.
Izitena eziphakamileyo ze-alumina zisetyenziswa ikakhulu kwimveliso yentsimbi, ishishini lesinyithi esingeyontsimbi kunye namanye amashishini.
Izitena ze-Mullite zisetyenziswa kuzo zonke iintlobo zesithando somlilo esine-hot-face lined kunye ne-backing lining kwi-metallurgical industry, i-petrochemical industry, ishishini lezinto zokwakha, ishishini le-ceramic, kunye neshishini lomatshini.
Izitena zeCorundum zinokusetyenziswa kwiziko eliqhumayo, isitovu esitshisayo, isitofu seglasi kunye nokunye.
