Superhard sp3 amorphous carbon block material with high thermal conductivity and preparation method of superhard sp3 amorphous carbon block material
The invention belongs to the field of amorphous carbon materials, and particularly relates to a superhard sp3 amorphous carbon block material with high thermal conductivity and a preparation method of the superhard sp3 amorphous carbon block material. The preparation method comprises the following steps: carrying out high-temperature and high-pressure treatment on C70 powder at the temperature of 900-1200 DEG C and the pressure of 18-30 GPa to obtain the sp3 amorphous carbon block. According to the preparation method, the short/medium-range ordered structure in the sp3 amorphous carbon can be regulated and controlled, the heat conduction property of the sp3 amorphous carbon material is remarkably improved, and meanwhile the mechanical property of the sp3 amorphous carbon material can be improved.
本发明属于非晶碳材料领域，具体涉及一种具有高热导率的超硬sp3非晶碳块材及其制备方法。所述制备方法包括：将C70粉末在900～1200℃的温度下，以及在18～30GPa的压力下，进行高温高压处理，以得到所述sp3非晶碳块材。本发明的制备方法能够调控sp3非晶碳内部的短/中程有序结构，显著提升sp3非晶碳材料的热传导性质，同时能提升其力学性质。
