摘要:: 中国是世界上最大的原材料生产国和消费国，但在许多核心科技产业的关键零部件的选材上仍然严重依赖进口原材料，面临着众多“卡脖子”问题，从根本上限制了我国高新材料产业和制造业的自主发展与快速升级。从我国原镁产业的现状出发，阐述了原镁中的杂质对镁合金和海绵钛等下游产品的影响，分析了现有金属镁纯化方法的局限性，并以国家自然科学基金委历年来的经费支持分布为依据，探究了造成目前镁产业现状的深层次原因。进而指出在国家层面加大对高纯镁及其他高纯原材料在基础研究上的投入，对促进我国原材料产业及相关下游产业的提质升级、提升我国材料产业战略安全系数等方面具有重要意义。

Abstract:: China is known as the largest producer and consumer of raw materials all over the world. However, the materials for key component in many of our high-tech industries are still heavily relying on imported high quality raw materials. This has caused lots of “bottle neck” problems, which are seriously threatening the independent development and rapid upgrade of China‘s manufacturing industry, especially under such an increasingly complex international environment. Starting from introducing the current situation of the raw magnesium industry, this article clarified the impact of impurities on the downstream products, such as magnesium alloys and titanium sponge, analyzed the restriction of the traditional purification methods and explored the root cause of the current situation. Furthermore, this article pointed out that greater attention and more investment should be paid to the fundamental research on highpurity magnesium and other high-purity raw materials, which has great importance in promoting the upgrading of China’s raw materials industry and the downstream industries as well as improving the strategic safety factor of related industry.
