Corrosion of engineering ceramic materials by molten iron Part II: Alumina
Source abstract
Abstract
Abstract The corrosion resistance of two different polycrystalline materials based on the alumina (with and without sintering additives) in molten iron at 1600 °C has been investigated. The corundum without sintering additives was the most corrosive resistant among all investigated materials at studied conditions. Significant changes in microstructure has been detected in corundum prepared with CaO·5SiO 2 (5 wt%) as a sintering additives due to the presence of anorthite Ca(Al 2 Si 2 O 8 ) at the grain boundaries and triple points. In the present work the influence of exposure time on the residual strength of the polycrystalline materials has also been estimated.
