Solution-Based Synthesis of Hafnium Carbide (HfC) Powders

Article Preview

Abstract:

HfC-based precursors with a range of carbon/metal oxide ratios were prepared from polymerization and copolymerization of metal containing monomers during solution-based synthesis. Heat treatments were given to the precursors to produce HfC powders. FTIR was used to record the infra-red spectra of the preceramic powders. HfC powders were assessed using X-ray diffraction and scanning electron microscopy.
