Izingubo zokulala ze-ceramic fiber ngokuvamile zakhiwa imicu ye-alumina-silica. Le micu yenziwe ngenhlanganisela ye-alumina (Al2O3) kanye ne-silica (SiO2) exutshwe nenani elincane lezinye izithasiselo ezifana nezihlanganisi kanye nezihlanganisi. Ukwakheka okuqondile kwengubo yokulala ye-ceramic fiber kungahluka kuye ngomkhiqizi kanye nokusetshenziswa okuhlosiwe.
Ngokuvamile, izingubo zokulala ze-ceramic fibre zinephesenti eliphezulu le-alumina (cishe i-45-60%) kanye ne-silica (cishe i-35-50%). Ukwengezwa kwezinye izithako kusiza ekuthuthukiseni izakhiwo zengubo, njengamandla ayo, ukuguquguquka kwayo, kanye nokuqhuba kwayo ukushisa.
Kuyaphawuleka ukuthi kukhona futhi okukhethekileizingubo zokulala zefayibha yobumbaezitholakalayo ezenziwe ngezinye izinto zobumba, njenge-zirconia (Zr2) noma i-mullite (3Al2O3-2SiO2). Lezi zingubo zingase zibe nokwakheka okuhlukile kanye nezakhiwo ezithuthukisiwe ezenzelwe ukusetshenziswa okukhethekile kwezinga lokushisa eliphezulu.
