Characterization and application of porous Ti3SiC2 ceramic prepared through reactive synthesis

• A novel porous material Ti3SiC2 with controllable structure is synthesized.
• The synthesized porous Ti3SiC2 presents excellent corrosion resistance in concentrated acids.
• Porous Ti3SiC2 is successful applied in the refined purification of ZnSO4 solution.

Porous ternary compound Ti3SiC2 with purity of higher than 99.0 wt.% was fabricated through a reactive synthesis method using titanium hydride, silicon and graphite elemental powders. The parameters of pore structure including the maximum pore size, open porosity and air permeability, obey the Hagen–Poiseuille formula with the constant G = 0.226 m−1 Pa−1 s−1 for the reactively synthesized porous Ti3SiC2. The porous Ti3SiC2 shows excellent corrosion resistance in concentrated acids. Further, a typical filter application in zinc metallurgy has been reported. The excellent overall performance predicts the porous Ti3SiC2 material has a broad application in industry.
