摘要:

中國是世界上最大的原材料生產國和消費國，但在許多核心科技產業的關鍵零部件的選材上仍然嚴重依賴進口原材料，面臨著眾多“卡脖子”問題，從根本上限制了我國高新材料產業和制造業的自主發展與快速升級。從我國原鎂產業的現狀出發，闡述了原鎂中的雜質對鎂合金和海綿鈦等下游產品的影響，分析了現有金屬鎂純化方法的局限性，并以國家自然科學基金委歷年來的經費支持分布為依據，探究了造成目前鎂產業現狀的深層次原因。進而指出在國家層面加大對高純鎂及其他高純原材料在基礎研究上的投入，對促進我國原材料產業及相關下游產業的提質升級、提升我國材料產業戰略安全系數等方面具有重要意義。

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�瞤urity 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.
