| Outline of Final Research Achievements |
Rigid Media Tube Filters (RMF) bonded to coarse-grained alumina by aluminum borate reaction bond layer (9Al2O3 2B2O3; 9A2B) are used to remove solid impurities from the molten aluminum. Molten aluminum corrodes the 9A2B bond layer. To improve corrosion resistance of the RMF, we examined yttrium titanate (Y2Ti2O7 ; YT) coating using YT aqueous precursor solution. As results of the corrosion resistance evaluation of the filters in the molten aluminum, a 9A2B bond layer of the coarse alumina was corroded about 2 weeks, but that 5 coats of YT remained for over 4 weeks.
