Inkcazo
Izitena eziphezulu ze-alumina luhlobo lwe-refractory, inxalenye ephambili ye-Al2O3. Ukuba umxholo we-Al2O3 uphezulu kune-90%, kuthiwa yi-corundum brick. Ngenxa yezibonelelo ezahlukeneyo, imigangatho yamazwe ahlukeneyo ayihambelani ngokupheleleyo. Ngokomzekelo, kumazwe aseYurophu, umda ophantsi we-Al2O3 umxholo we-alumina refractories ephezulu yi-42%. E-China, umxholo we-Al2O3 kwizitena eziphezulu ze-alumina zihlukaniswe ngokubanzi ngamabakala amathathu: iBanga I-Al2O3 umxholo> 75%; ibakala II - Al2O3 umxholo 60-75%; ibakala III - Al2O3 umxholo 48-60%.
Iimbonakalo:
1.Ukunyaniseka okuphezulu
2.Amandla aphezulu obushushu
3.Ukuzinza okuphezulu kwe-thermal
4.I-refractory engathathi hlangothi
5.Ukuchasana okuhle kwi-asidi kunye nesiseko se-slag corrosion
6.I-refractoriness ephezulu phantsi komthwalo
7.Ubushushu obuphezulu bokuxhathisa
8.I-porosity ephantsi ebonakalayo

Isicelo:
Izitena eziphakamileyo ze-alumina zithandwa kakhulu kwi-masonry ye-kilns ye-inner linings yangaphakathi, efana neendawo eziqhumayo, i-hot blast furnaces, i-top electric furnace, i-reverberator, i-rotary cement kiln njalo njalo. Ngaphandle koko, izitena eziphezulu ze-alumina zikwasetyenziswa ngokubanzi njengezitena zokujonga ukuhlaziya, isithinteli senkqubo eqhubekayo yokuphosa, izitena ze-nozzle, njl.
