Polysilazane (PSZ), which a precursor for SiCN ceramics, has been attracting much attention for the metal/ceramic composites. Before pyrolysis, PSZ is soluble in many organic solvents and can be easily mixed with metal precursor. After pyrolysis, SiCN/metal composites can be manufactured in which the metal is uniformly distributed in the SiCN ceramic matrix. For the above reasons, the SiCN/metal composite prepared using PSZ as a precursor can be used for EMI shielding, membrane, catalysis, and 3D printing. In this study, we prepared SiCN/nickel (Ni) composite using silsesquiazane (SSQZ) as a precursors. Since the SSQZ has a branched structure and more amine groups than linear PSZ, the Ni precursor can be uniformly dispersed. In order to confirm the morphology of the SiCN/Ni composites, we conducted the analysis of the XRD, BET, FE-SEM, FE-TEM and EDS. In addition, morphology changes of SiCN/Ni composite with Ni content of weight ratio and pyrolysis temperature were also confirmed. |
