天津铱粉的应用与回收

Core Viewpoint - Iridium is a rare precious metal with significant applications in high-end industrial, technological, and research fields, particularly in Tianjin, China, where its application and recycling are becoming increasingly important [1]. Application Areas of Iridium Powder - Iridium powder is primarily used in chemical catalysts, especially in petroleum refining and organic chemical reactions, due to its high-temperature resistance, corrosion resistance, and strong catalytic activity [2]. - In the electronics industry, iridium powder is widely used in manufacturing electrical contact materials, switches, and relays, making it essential for high-end electrical equipment, particularly in aerospace and military communications [4]. - Iridium powder plays a crucial role in high-temperature alloys, being a key component in alloy materials for advanced equipment like aircraft engines and rocket engines, ensuring stability and longevity in extreme high-temperature environments [5]. - In the medical field, iridium powder is utilized in the production of certain radioactive drugs, particularly in targeted radiation therapy for cancer treatment [6]. Importance and Market Outlook of Iridium Powder Recycling - The recycling of iridium powder has significant economic and environmental value globally, as it reduces resource waste and lowers production costs, making it an important industry trend in industrial hubs like Tianjin [8]. - The main sources for iridium powder recycling include waste catalysts, discarded electronic components, and industrial waste, with high-precision chemical separation technology required to extract iridium from these sources [9]. Recycling Prices - The recycling price of iridium powder is relatively high, typically ranging from 350 to 500 RMB per gram in Tianjin, influenced by market demand and supply conditions, as well as fluctuations in prices of other precious metals like palladium and platinum [10]. Challenges and Technical Requirements in Recycling - Despite the significant economic benefits of iridium powder recycling, technical challenges remain, including the need for precise chemical purification processes and advanced equipment to meet high purity requirements [11]. Future Prospects of Iridium Powder Recycling in Tianjin - With the increasing global demand for rare metals, the iridium powder recycling industry is expected to mature, particularly in Tianjin, which has strong production and technical foundations [12]. - The growing demand for iridium in sectors such as new energy, electronics, and aerospace, along with stricter environmental policies and improved legal frameworks, will enhance the efficiency and economic benefits of iridium powder recycling [12].
