重要稀土氧化钇，价格飙升

Core Insights - The price of yttrium, a rare earth element widely used in military, aerospace, and semiconductor industries, has surged due to supply constraints, with prices rising from approximately $6 per kilogram to between $220 and $320 per kilogram, representing an increase of 3600% to 5300% [1] - Yttrium is essential for high-performance applications such as special alloys in jet engines and dielectric layers in semiconductor manufacturing [1] - The supply chain for yttrium is heavily reliant on imports from China, with over 90% of yttrium oxide imports to the U.S. coming from China in the past four years [1] Supply Chain and Market Dynamics - The U.S. aerospace industry is significantly affected by the yttrium supply shortage, leading to increased costs due to reliance on Chinese imports [1] - The semiconductor industry is also facing severe concerns regarding yttrium shortages, with one industry insider indicating the shortage's severity at "nine out of ten" [2] - Inventory levels in the yttrium market are highly variable, with reports of one trader's stock dropping from 200 tons to just 5 tons [2] Future Outlook - Analysts suggest that unless there is a significant increase in supply, yttrium prices are unlikely to decrease substantially [3] - Companies like MP Materials and Lynas Rare Earths are working to increase yttrium production, with MP Materials extracting yttrium from its Mountain Pass project and Lynas expanding capacity at its Mount Weld mine and processing plant in Malaysia [3] - ReElement Technologies plans to boost yttrium oxide production to 200 tons annually by December, with ambitions to double that output in the following year [3]
