Izitena ze-silica-mullite zahlulwe zibe ngamanqanaba amathathu: GM1650, GM1600, kunye ne-GM1550 ngokomthwalo wokuthambisa ipharamitha yobushushu.

Izitena ze-silica-mullite zinezi mpawu zilandelayo:

① Ulwakhiwo lwemveliso luxinene kwaye lunokungagugi kakuhle. Ulwakhiwo lweemveliso zezitena ze-silica-mullite zixinene, kwaye ubuninzi bomthamo ngokuqhelekileyo yi-2.55 ~ 2.65g/cm³. Ngenxa yobuninzi bayo obugqwesileyo, amandla kunye nokumelana nokunxiba, isetyenziswa kakhulu kwi-samente ye-rotary kiln amabhanti okudubula yesibini, amabhanti okucoca kunye nezinye iindawo.

② Umthwalo ophezulu wokuthambisa iqondo lokushisa kunye nokusebenza kakuhle kweqondo lokushisa eliphezulu. Ubushushu bokuthambisa umthwalo wezitena ze-silica-mullite zingaphezulu kwe-1450℃, kwaye elona liphezulu linokufikelela ngaphezulu kwe-1650℃.
