微卷曲ZrC纤维是通过使用ZrCl4+H2+Ar气体混合物在1100-1250℃下对微卷曲碳纤维进行气相金属化而制备的。研究了所得ZrC线圈的制备条件、形貌和体电阻率。即使在这种处理之后，源卷曲碳纤维的卷曲形态也被完全保留。卷绕 ZrC 纤维的体积电阻率随着体积密度的增加而降低，在 0.8 g cm−3 时为 10−1s−1cm。
Micro-coiled ZrC fibres were prepared by the vapour phase metallizing of micro-coiled carbon fibres using a ZrCl4+ H2+ Ar gas mixture at 1100–1250 °C. The preparation conditions, morphology and bulk electrical resistivity of the obtained ZrC coils were examined. The coiling morphology of the source coiled carbon fibres was fully preserved even after this treatment. The bulk resistivity of the coiled ZrC fibres decreased with bulk density and was 10−1s−1cm at 0.8 g cm−3.
