Abstract

Prismatic SiC fibers with periodic serrated structure, mostly reaching millimeter-sized lengths, were synthesized by a simple catalyst-free method. The process involved heating SiC nanopowder in a graphite crucible at 1700°C under 0.1-MPa argon atmosphere. The synthesized SiC products consist of SiC fibers several millimeters in length and mostly 0.5–3 µm in diameter. Further, the vapor-solid growth mechanism and detailed growth process of SiC fibers are discussed. The millimeter-sized prismatic SiC fibers have the potential to be applied in fields such as electromagnetic wave absorption.

用无催化剂热蒸发法制备毫米尺寸的棱镜碳化硅纤维

采用简单的无催化剂方法合成了具有周期性锯齿结构的棱柱状SiC纤维，其长度大多达到毫米级。该工艺是在石墨坩埚中加热SiC纳米粉末，温度为1700℃，氩气温度为0.1 mpa。合成的SiC产品由SiC纤维组成，长度为几毫米，直径大多为0.5-3µm。进一步讨论了碳化硅纤维的气固生长机理和详细的生长过程。毫米尺寸的棱镜SiC光纤在电磁波吸收等领域具有潜在的应用前景。
