稀世珍宝现身我国，西方想拿先进技术来换，被我国直接拒绝

Core Viewpoint - The discovery of a rhenium mine in Shaanxi, China, with reserves of 176 tons, positions China as the fourth-largest rhenium resource country globally, igniting strategic competition among nations, particularly involving Western military-industrial interests [1][3]. Group 1: Rhenium's Strategic Importance - Rhenium, with a melting point of 3186°C, is rarer than all rare earth elements combined and is essential for manufacturing single-crystal turbine blades in aerospace engines, earning it the title of "industrial vitamin" [1]. - The strategic negotiations involving Western countries, including the U.S., U.K., France, and Germany, aim to exchange outdated technical blueprints for rhenium resources, exploiting China's potential lack of understanding of critical knowledge [3][5]. Group 2: Risks of Technology Transfer - The proposed exchange of F-135 engine blueprints for 50 tons of rhenium is viewed as a deceptive deal, as the blueprints do not provide essential insights into the alloy's micro-element composition or the single-crystal growth process [3][5]. - The Western strategy is perceived as a calculated move to turn China into a low-cost supplier of strategic resources, undermining its aerospace industry and trapping it in low-end assembly roles [5]. Group 3: Domestic Technological Challenges - Chengdu Aerospace Superalloy Technology Co., Ltd. achieved breakthroughs under severe technological restrictions, highlighting the challenges faced by Chinese engineers due to Western embargoes on advanced equipment [7]. - The introduction of semiconductor-grade heat treatment furnaces into aerospace applications represents a desperate yet innovative response to these challenges, although it involves high costs and uncertainties due to the lack of existing reference data [8]. Group 4: Progress and Future Outlook - Despite achieving standards comparable to Western counterparts in producing rhenium-containing blades by 2016, significant hurdles remain in achieving stable production and industrial-scale manufacturing [10]. - Jiangxi Copper successfully produced 99.99% pure rhenium powder in 2023, marking progress in upstream resource development, but the industry still lags behind established global players who have decades of experience [10].
