Slag corrosion resistance of Al4SiC4
-
Chao Yu
Abstract
Powdered mixtures of Al2O3/SiO2/C/Al were heated together to synthesize Al4SiC4 and the corrosion resistance of the Al4SiC4 product was subsequently investigated. The results show that the addition of aluminium accelerates the synthesis of Al4SiC4. The slag corrosion resistance of the Al4SiC4 product is excellent (as determined using the static-crucible method). At high temperatures, the surface of the Al4SiC4 initially reacts with oxygen to form Al2O3 and SiO2. The Al2O3 formed dissolves in molten slag, and further reacts with MgO to form MgAl2O4. The above reaction processes can form a protective layer on the surface of the ternary carbide, which inhibits further corrosion of the Al4SiC4 material.
