Aluminium powders were introduced to Al2O3 -SiC-C dry ramming mixes in order to improve sintering properties and oxidation resistance according to their serv-ice conditions and installation methods. Properties such as bulk density, porosity, modulus of rupture, crushing strength and hot modulus of rupture as a function of alu-minium addition were investigated in the present work. The microstructure and thermodynamics for the heat trea-ted specimens were also analyzed. The results show that as aluminium addition increasing, the bulk density of the specimen treated at 220 ℃ tends to decrease and the ap-parent porosity increases, the strength of the specimens treated at 1 100 ℃ and 1 450 ℃ increases markedly, the bulk density tends to increase, apparent porosity and line-ar shrinkage decrease. The HMOR at 1 400 ℃ is en-hanced from 1.0 MPa to 3. 5 MPa with 3% aluminium. Aluminium is served as sintering agent and anti-oxidant and it will react with CO and CO2 forming Al2O3, which is helpful to enhance the strength, densify the structure and improve the overall properties.
