AlZrC₂ Synthesis

抄録

AlZrC₂ synthesis via solid state method was carried out. The effect of carbon in graphite and carbon atom in ZrC on AlZrC₂ formation was studied. Graphite and amorphous carbon were tested for AlZrC₂ preparation. Glassy carbon was effective for AlZrC₂ formation. However, a significant amount of Zr₂Al₃C₅ was found due to graphitization of glassy carbon at high temperature. Glassy carbon from sugar showed the lower degree of crystallization (graphitization) than glassy carbon from phenolic resin at 1600^oC in vacuum. Therefore, AlZrC₂ with the lowest amount of Zr₂Al₃C₅ was synthesized from the appropriate mol ratio of Al, ZrC and amorphous carbon from Sugar at 1600^oC in vacuum for 1 h.
