| Abstract Scope |
HfC is a promising high-temperature material due to its high melting point, excellent thermal conductivity, and mechanical strength. Here, a commercial HfC precursor was used and characterized at different crosslinking temperatures ranging from 100 to 400 °C and pyrolysis temperatures from 1200 to 1600 °C. The present study focuses on their microstructure evolution at various temperatures in argon atmosphere. FTIR spectroscopy provided information on the chemical composition and functional groups present in the precursor molecules at various stages of cross-linking process. 1H and 13C NMR spectrum showed the chemical shifts of the nuclei, which was used to identify the types of atoms and the nature of the chemical bonds within the HfC precursor. In addition, XPS was used to gather information on the chemical composition and electronic structure of the precursor and ceramics. Studies on low-temperature synthesis and low-cost precursors are among the main emphases of ongoing research efforts. |
