Strong Shock-Compression of g-C3N4 Precursor for Direct Synthesis of -C3N4

  • 摘要: 为了合成出理论预言的具有致密结构的超硬材料C3N4,运用二级轻气炮加载和冲击回收实验技术,以富含N的g-C3N4为前驱物,在40~65 GPa压力下完成了冲击合成实验。在低于51 GPa压力时,X射线衍射分析表明,在回收样品中未发现有新相生成,说明g-C3N4是稳定的;而在51~65 GPa范围内,回收样品中有新相生成,与理论计算结果对照发现,新相为-C3N4相,且不含其它结晶相。证实利用冲击合成方法将g-C3N4直接转化为单纯-C3N4是可能的,对纯净的超硬相碳氮化合物的合成研究具有参考意义。
