“…Initial static and dynamic corrosion testing of this material, along with sessile drop testing, showed that this material showed nonwetting behavior on the macroscopic level and only slight wetting behavior on a microscopic level 6 . Additionally, exposures of up to 500 h in contact with molten aluminum showed only minimal interaction of the material with the molten metal and the formation of a passivating layer on the refractory surface, which served to protect the refractory from further reaction as shown in Fig.…”

Two new refractory materials have been developed for use in molten aluminum contact applications that exhibit improved corrosion and wear resistance leading to improved thermal management through reduced heat losses caused by refractory thinning and wastage. The development of these materials was based on an understanding of the corrosion and wear mechanisms associated with currently used aluminum contact refractories through physical, chemical, and mechanical characterization and analysis performed by Oak Ridge National Laboratory (ORNL) and the University of Missouri, Rolla Rolla (UMR), along with their industrial partners, under the ITP Materials project ''Multifunctional Metallic and Refractory Materials for Energy Efficient Handling of Molten Metals.'' Spent castable refractories obtained from a natural gas-fired reverberatory aluminum alloy melting furnace were analyzed, leading to identification of several refractory degradation mechanisms and strategies to produce improved materials. The newly developed materials have been validated through an R&D industrial trial.
