Quantitative determination of ZrC in new ceramic materials by Fourier transform infrared spectroscopy

Fabrication of biomorphic ZrC/C ceramics by sol–gel and carbothermal reduction processing

“…Although ZrC ceramic can be synthesized via sol-gel method using Zr-alkoxides as precursors, there are still several drawbacks such as high cost, toxicity and the difficulty to determine C/Zr molar ratio due to the pyrolyzed carbon brought by the alkoxide. To overcome those drawbacks, inorganic precursors like zirconium oxychloride previously have been used to synthesize some advanced ZrC materials such as ultra-fine ZrC powders [20] and ZrC-based biomorphic ceramics [21] by sol-gel method. However, so far to the authors' best knowledge, no experimental study has been published pertaining to the application of zirconium oxynitrate as zirconium source in the fabrication of biomorphic ZrC ceramics by sol-gel and carbothermal reduction processing.…”
