Isitena somlilo seSlilica mullite senziwe ikakhulu nge-mullite njengeyona nto iphambili kwaye iqulathe ngaphezulu kwe-30percent yeSiO2 umxholo kunye neepesenti ezingama-60 ze-Al2O3. I-slilica mullite refractoriness yezitena zomlilo ngokubanzi ingaphezulu kwe-1580 degree. isitena somlilo se-silicate mullite siqulunqwe kakhulu yi-mullite, i-corundum, i-SiC kunye neglasi. isitena se-silicon ye-mullite se-refractory senziwa ekudibaneni kweegranules njenge-mullite, iglasi kunye ne-SiC. i-silicate mullite firebrick enomgangatho ophezulu kunye neempawu ezahlukeneyo ezigqwesileyo zokusetyenziswa kuzo zonke iintlobo zeziko lobushushu obuphezulu kunye neetoni, ezifana neziko lokutshisa.
Ibhloko yeSilicon mullite yenziwe ngezinto ezikrwada zomgangatho ophezulu we-bauxite kunye ne-SiC kunye nenkqubo ekhethekileyo ye-sintering. Izitena ze-silica mullite zibonakaliswe ngoxinaniso oluphezulu, ukusebenza kakuhle kokuxhatshazwa kwe-abrasion kunye nokuxhatshazwa kwe-thermal shock. ibhloko ye-silicate ye-mullite inokuhlala isenza umaleko okhuselayo wokunciphisa ukubunjwa kwe-accrection, umjikelo wesicelo omde.

I-Silicon mullite firebrick isetyenziswe kwintsimbi kunye nentsimbi, isinyithi esingenamvubelo, i-petrochemical, oomatshini, umbane, imboni yokukhanya kunye namanye amashishini asisiseko anoluhlu olubanzi lwezicelo. Imimandla ephambili yesicelo sezinto eziphikisayo kunye nemilinganiselo yazo ehambelanayo kwishishini lensimbi libalelwa kwinani elikhulu. Kwaye isitena se-silicon mullite sisetyenziswa ngokubanzi kuzo zonke iintlobo zemizi-mveliso yentsimbi kunye nentsimbi, i-petrochemical, isinyithi esingenamvubelo, oomatshini, umbane, isakhiwo njalo njalo.
Umzi-mveliso we-RS refractory njengomvelisi we-silicon mullite firebrick e-china, uneenzuzo ezininzi zokukhuphisana kwimarike. Kwaye njengomthengisi wezitena zomlilo we-silicon mullite e-China unokubonelela ngekhwalithi ephezulu kunye nexabiso eliphantsi le-silicate mullite firebrick. Itekhnoloji yemveliso ephezulu kunye nezixhobo zokuvelisa zibonelela ngesiseko somgangatho wethu wezitena ze-silicate mullite. ukuba unemfuno ye-silica mullite yesitena somlilo okanye unemibuzo malunga ne-silicon mullite fire block malunga neempawu ezibonakalayo kunye neekhemikhali, nceda uqhagamshelane nathi simahla, siya kukubonelela ngezitena ezikumgangatho ophezulu wesilicon mullite.
