Characterization and application of porous Ti3SiC2 ceramic prepared through reactive synthesis

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. (C) 2015 Elsevier Ltd. All rights reserved.
