Abstract
The corrosion behaviour of MoSi2-15%HfO2 composites was investigated under simulated Pressurized Pulverized Coal Combustion (PPCC) conditions at 1450 °C in the presence of liquid slag. The composites form a dense glassy corrosion product layer which consists mainly of SiO2 and HfSiO4. The specimens show relative good corrosion resistance against coal slag in comparison to most commercial available ceramic materials.
