Since carbon nanotubes (CNTs) have excellent mechanical, electrical, and thermal properties, as well as chemical inertness, large aspect ratio, and high surface area, research has been actively conducted to apply those characteristics in the composite material field. In this study, we used phenyl silsesquiazane (SSQZ) as a precursor to silicon carbonitride (SiCN) ceramics. SSQZ was mixed with nickelocene and pyrolyzed to form SiCN ceramics. During the process, it was observed the growth of CNTs in the ceramic matrix. The formation of CNTs was studied by changing pyrolysis time, temperature, and amount of nickel precursor using XRD, FE-SEM, EDS, and FE-TEM.
