This work proposed to prepare SiC membranes by uniformly coating AlOOH sol on SiC particles via the electrostatic interaction and the subsequent reaction sintering of the derived SiC@alumina core-shell particles. It is found that the surface coating enabled the homogeneous dispersion of the additives in SiC powder matrix, which not only facilitated the reactive sintering process and notably reduced the amount of residual SiO<sub>2</sub> in SiC membranes, but also homogenized the pore structure. Also, the oxidation pathway of SiC had been altered, which substantially retarded the oxidation degree. Impressively, the as-prepared SiC membranes exhibited 20 % improvement in alkali resistance, and enhanced oil-in-water emulsion separation efficiency when compared with those prepared by the conventional mechanical mixing method.
