The corrosion of refractories along with fracture processes are their two most important degradation phemonena. Unfortunately, corrosion has come to mean a number of different degradation processes, such that there is no single unifying mechanism of corrosion, or sequential series of events relative to the refractory corrosion process in general. Several of these phenomena are addressed as are the experimental laboratory tests for the corrosion resistance and comparison of different refractories. Some of the related basic phenomena such as wetting, by both molten metals and slags are considered for wetting is an important aspect of some forms of corrosion. Anti -wetting agents are discussed as well as their roles in corrosion by molten aluminum. Several directions of future research are suggested.
The above in the talk. I will also discuss some of our research on the wetting by molten aluminum and the Ba anti-wetting agents. The wetting phenomena is important, but poorly understood.
