HfxZr1-xC ceramic solid solution nanowire and preparation method thereof
The invention relates to an HfxZr1-xC ceramic solid solution nanowire and a preparation method. The method comprises: respectively weighing precursors with different masses, and configuring accordingto different molar ratios; and preparing the HfxZr1-xC solid solution nanowire on the surface of a carbon/carbon composite material by adopting a low-pressure chemical vapor deposition (LPCVD) technology. The atomic molar ratio in the solid solution nanowire can be regulated and controlled by regulating and controlling the content of each component in the mixed precursor powder, and the microstructure of the solid solution nanowire can be effectively controlled by regulating and controlling LPCVD process parameters. The preparation process is simple and easy to operate, the morphology of the nanowire can be effectively controlled, and the application of the nanowire in the fields of various materials is expanded.
本发明涉及一种HfxZr1‑xC陶瓷固溶体纳米线及制备方法，分别称取不同质量的前驱体，按照不同摩尔比例进行配置。采用低压化学气相沉积(LPCVD)技术在碳/碳复合材料表面制备出HfxZr1‑xC固溶体纳米线。通过对混合前驱体粉料中各组分含量调控可实现对固溶体纳米线中原子摩尔比进行调控,以及对LPCVD工艺参数的调控可对固溶体纳米线的微观结构进行有效的控制。本发明制备工艺简单易操作，可对纳米线形貌进行有效的控制，拓展其对在多种材料领域中的应用。
