Structural evolution and oxidation resistance of polysilazane‐derived SiCN–HfO2 ceramics
Journal of the American Ceramic Society, Volume 107, Issue 3, Page 1657-1668, March 2024.Abstract Polymer‐derived SiCN materials have great application potential in high‐temperature environments. In the current work, SiCN ceramics were tailored with Hf incorporation through doping of a molecular precursor in the preceramic polymer. The ceramics remained in a single amorphous phase up to 900°C.
