[PDF] Coal-ash corrosion of monolithic silicon carbide

Abstract Several silicon carbide-based monolithic refractories were subjected to static coal ash corrosion tests to determine corrosion mechanisms and rates. Two castable refractories with 75% and 85% SiC were exposed to two types of coal ash at temperatures from 1090°C to 1430°C. Several plastic refractories were exposed to a high-calcium coal ash at 1430°C for over 100 h.
