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 highpurity 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.
