isitini esigobile esiphikisayo siqukethe i-Al2O3 cishe u-30% ~ 45%, futhi okuqukethwe kwe-silica kungaphansi kuka-78%. izitini eziphikisayo ezigobile ziyingxenye ye-acid refractory ebuthakathaka. i-curved refractory block imelana ne-asidi slag kanye nokuguguleka kwamagesi ane-asidi, kodwa amandla okumelana ne-alkali ampofu kancane. amabhulokhi aphikisayo agobile anezinhlamvu zokusebenza okuhle kokushisayo kanye nokumelana nokushaqeka okuhle kokushisa.

I-firebrick egobile isetshenziselwa ikakhulukazi ulwelwesi oluvikelayo lwezindawo ezishisayo noma ukusekela izendlalelo ezivikela ukushisa zezinye izinto eziphikisayo. ama-linings aphikisayo noma izinto zokuvikela ukushisa zezimboni, njengeziko le-ethylene pyrolysis, izithando zamashubhu, izithando ezishintshayo ze-synthetic ammonia, amajeneretha egesi kanye neziko lokushisa eliphezulu le-shullte, njll.
