Zirconia ultrafiltration meranes on silicon carbide …

1/9/2020· In summary, a ZrO 2 /SiC ceramic merane was prepared with pure silicon carbide as the substrate and intermediate layer, and zirconia as the selective layer. Because of the exclusion of low-melting oxides, both the chemical corrosion and thermal resistances of the merane were improved, thus it could be used in strong acidic or alkaline conditions, or high temperature environment.
