Chiyambi cha kapangidwe ka mullite wosakanikirana
Zosakaniza za mullite nthawi zambiri zimagwiritsa ntchito aluminiyamu yapamwamba kwambiri, bauxite yachitsulo, aluminiyamu yamafakitale ndi dongo losungunuka ngati zopangira. Kusankhidwa koyenera kwa zosakaniza ndi njira yofunikira yokonzekera njerwa zosakanikirana ndi zinthu zambiri za mullite ndi magawo otsika a corundum ndi magalasi. Chokwanira cha okosijeni cha aluminiyamu cha zosakaniza chimayimira zomwe zili mu Al2O3 ndi SiO2 muzosakaniza, ndipo mosadziwika bwino zimawonetsa kuchuluka kwa mullite wopangidwa mu njerwa yosakanikirana. Onjezerani pang’ono chochepetsera (malala kapena coke yabwino) ku zosakaniza. Kuti mpweya wopangidwa panthawi yosungunula ukhale wosavuta kuthawa, zitsulo zazing’ono zamatabwa ziyenera kuwonjezeredwa kuzinthuzo, ndipo kusungunuka kuyenera kuchitika pa kutentha kwa 900-2200 ° C.
