isitena esigobileyo esichasayo siqulethe i-Al2O3 malunga ne-30% ~ 45%, kunye nomxholo we-silica ungaphantsi kwe-78%. izitena ezigobileyo zerefractory zezemathiriyeli ye-asidi ebuthathaka. Ibloko egobileyo echasayo iyaxhathisa kwi-acid slag kunye nokhukuliseko lweegesi ze-asidi, kodwa isakhono sokumelana ne-alkali sibi kancinci. iibhloko ezigobileyo ezigobileyo zineempawu zokusebenza kakuhle kwe-thermal kunye nokumelana nokothuka kwe-thermal.

I-firebrick egobileyo isetyenziselwa ubukhulu becala ukugquma indawo eshushu okanye ukuxhasa iileya ezikhusela ubushushu zezinye izinto ezichasayo. i-refractory linings okanye izinto ezikhusela ubushushu zamashishini, ezifana ne-ethylene pyrolysis furnaces, ii-tubular furnaces, ii-furnaces ezilungisayo ze-synthetic ammonia, iijenereyitha zegesi kunye ne-shullte kilns yobushushu obuphezulu, njl.
