Synthesis of zirconium carbide powders using chitosan as carbon source
Source abstract
Abstract
Abstract Chitosan–zirconium complex, obtained by chelation of chitosan to zirconium, formed a novel precursor for zirconium carbide (ZrC). ZrC was synthesized via carbothermal reduction reaction using zirconium oxychloride (ZrOCl 2 ·8H 2 O), and chitosan as sources of zirconium and carbon. The initiation of carbothermal reduction process was at about 1400 °C, and the reaction was substantially completed at a relatively lower temperature (∼1550 °C), compared with that using ZrOCl 2 ·8H 2 O and phenolic resin as a carbon source. The conversions from as-synthesized preceramic precursors to ceramics were studied by means of FTIR, DSC-TG, SEM, EDS and XRD.
