Maybe not. Yttrium oxide and zirconium oxide both form very stable ceramics (yttrium stablized zirconia is very tough stuff and very corrosion resistant). But I'm not sure how they will behave as minor components in some system and the radiochemistry changes this (radiation damage to solids, particularly alpha particle and neutron damage)
