Abstract
Polymer Derived Ceramics (PDCs) are synthesized by converting liquid polymer precursors into ceramics through controlled pyrolysis. This study focuses on silicon carbonitride (SiCN) ceramics obtained from Ceraset Polysilazane (Durazane1800) precursor. The influence of pyrolysis atmospheres, including inert (Ar, N2) and reactive (H2) environments, on the thermal conversion of Durazane1800 into SiCN ceramics is investigated. The resulting ceramics' chemical variations are explored through phase analysis using X-ray diffraction (XRD), Raman spectroscopy, and thermogravimetric analysis (TGA). Notably, the impact of hydrogen versus nitrogen atmospheres on the conversion process is analyzed, shedding light on their distinct contributions to the composition and properties of SiCN ceramics. The findings contribute to a comprehensive understanding of PDC synthesis, offering insights into tailoring ceramics for diverse applications.
