Synthesis of hafnium carbide (HfC) via one‐step selective laser reaction pyrolysis from liquid polymer precursor

Journal of the American Ceramic Society, Volume 108, Issue 9, September 2025.
➢ A one‐step selective laser reaction pyrolysis (SLRP) technique was developed to rapidly synthesize hafnium carbide (HfC) from liquid polymer precursors. ➢ XRD and TEM confirmed the nanocrystalline structure of the HfC. ➢ The SLRP‐based process achieved up to 54% ceramic yield, 18% higher than furnace‐based methods.

Exceptional Hardness and Thermal Properties of SiC/(Hf,Ta)C(N)/(B)C Ceramic Composites Derived from Single‐Source Precursor

Advanced Engineering Materials, Volume 26, Issue 17, September 2024.
Si(B)C/(Hf0.75Ta0.25)C(N)/C ceramic composites are prepared via spark plasma sintering of amorphous SiHfTaBCN‐based powders. The inclusion of boron led to enhanced densification and great homogeneity of the microstructure, besides decreasing the thermal conductivity and increasing the Vickers hardness (31 GPa) as well as the Young's modulus (405 GPa ...

Thermal Conductivity Analysis of Polymer‐Derived Nanocomposite via Image‐Based Structure Reconstruction, Computational Homogenization, and Machine Learning

Advanced Engineering Materials, Volume 26, Issue 17, September 2024.
Establishing a structure–property relation (SPR) is crucial for tailored material design. Herein, an SPR is developed using machine learning (ML) on microstructural and thermal data, validated by experiments. A diffuse‐interface model handles the complexity of the microstructure to calculate the effective thermal conductivity by finite element methods.
