“稀世珍宝”再现我国，多国想用先进技术换购，都被我国一一拒绝

Core Insights - Technological advancement is crucial for rapid national development, which relies on the support of natural resources, highlighting the importance of rare minerals like rhenium [1][9] - Rhenium, a rare metal with a boiling point exceeding 5,500 degrees Celsius, is one of the scarcest elements globally, with proven reserves of less than 2,500 tons [3] - China's recent discoveries of rhenium reserves, including 176 tons in Shaanxi and 30 tons in Anhui, have reduced its dependency on foreign sources and enhanced its strategic autonomy [5][8] Industry Significance - Rhenium plays a vital role in the aerospace industry, particularly in the manufacturing of aircraft engines, where it is essential for components like single-crystal turbine blades and combustion chambers [6] - The high cost of rhenium, approximately 300 RMB per gram, reflects its value and importance in various industrial applications, including nuclear energy and environmental purification [5][6] - The geopolitical implications of rhenium scarcity have led to international interest, particularly from the U.S., which has historically controlled Chile's rhenium resources to maintain its lead in the aerospace sector [8] Strategic Implications - As China strengthens its position in high-tech industries, the discovery of more rhenium resources will provide a solid foundation for its aerospace and technology sectors [9][11] - The determination to protect its resources signifies a shift in China's global standing, moving away from being a vulnerable nation to one that safeguards its strategic assets [9][11]
