碳化镍颗粒（Ni3C）Product overview
碳化镍颗粒是以高纯镍粉（≥99.9%）与纳米碳黑（≥99.95%）为原料，通过等离子体瞬时合成、低温化学气相沉积（CVD） 或机械合金化制备的亚稳态六方晶系材料（空间群：P6₃/mmc，晶胞参数：a=0.265 nm, c=0.433 nm）。其具备类金属导电（电阻率15-25 μΩ·cm）、超高催化活性（析氢过电位＜50 mV）、电磁波宽频吸收（2-18 GHz反射损耗＜-30 dB）及磁电耦合效应特性，专用于氢燃料电池催化剂、锂硫电池多功能隔膜、隐身涂层及磁存储材料。通过晶格应变调控（c/a比0.613-0.618）、表面配位修饰（N/S共掺杂）及亚稳态稳定化（Ni₃C@C核壳），满足新能源、电子对抗及先进存储对高性能碳化物材料的极限需求。
