摘要 石墨具有导电、耐热、韧性好、抗腐蚀、可塑性强、润滑性能好等优异性能,可广泛应用于冶金、机械、电子、化工、医学、国防、航天等行业,是当今高新技术发展必不可少的非金属材料。石墨的纯度决定着石墨产品的综合使用性能,然而石墨提纯关键技术掌握在美国等发达国家手中,我国的高纯石墨大多依赖进口。本文主要介绍了石墨不同提纯工艺的研究进展,包括提纯工艺原理、提纯条件和提纯设备等,为实现我国石墨资源的有效利用提供参考及借鉴。

Abstract: Graphite has excellent performance, such as electricity, heat resistance, good toughness, corrosion resistance, strong plasticity, good lubrication, which can be widely used in metallurgy, machinery, electronics, chemical industry, medicine, national defense, aerospace and other industries. It is an essential non-metallic material for the development of high-tech. The purity of graphite determines the comprehensive use performance of graphite products, but the key technology of graphite purification is control in the United States and other developed countries. China's high purity graphite mostly relies on imports. This article mainly introduced the research progress of different graphite purification processes, including the principles of purification process, purification conditions and purification equipments, which can provide reference for realizing the effective utilization of graphite resources in China.
