Summary

Ultra high-temperature ceramic filters with good oxidation, corrosion and creep resistances are strongly demanded for many applications. In this preliminary study, unidirectionally porous Zro2, has been successfully fabricated by using the Zro2-MgO eutectic reaction and the following HCl treatment to remove MgO. Unidiroectional pores of ∼300 nm in diameter were very uniformly distributed in the porous Zro2.
