Abstract:

By analysing phase diagram，the raw matericals，such as corundum，α-Al2O3 micro powder，spinel and fused magnesia and sol or/and brine composite binder for unburned carbon\|free alumina\|magnesia spinel brick were determined in this paper.The effects of different amounts of spinel powder，fused magnesia，chemical magnesia，α-Al2O3 micro powder，Cr2O3 fine powder and SiO2 micro powder on performance of carbon\|free alumina\|magnesia spinel brick were observed.
