Germanium prices surge over 80% driven by AI optical fiber demand · 1 source tracked

The price of germanium has surged by over 83% since the end of 2023, reaching 25,000 yuan/kg by June 18th. This significant price increase is primarily driven by the high demand for optical fibers in AI computing infrastructure. Germanium tetrachloride, a crucial component in optical fiber manufacturing, acts as a key additive to enhance core refractive index and improve transmission performance. Despite its small proportion in the cost of optical fiber preform raw materials, the stringent purity requirements and concentrated domestic supply of germanium, coupled with its non-substitutability, create a pronounced supply-demand imbalance. AI

IMPACT The surge in germanium prices highlights the critical role of specialized materials in scaling AI infrastructure, potentially impacting the cost and availability of advanced computing resources.

RANK_REASON Significant price increase of a key material driven by AI infrastructure demand. [lever_c_demoted from significant: ic=1 ai=0.7]

    Rare "MSG" supply-demand mismatch intensifies, germanium prices rise over 80% in half a year

    截至6月18日,锗锭已攀升至25000元/千克,较2025年末涨逾83%。驱动这一轮价格飙升的,主要是AI算力基础设施等领域对光纤的旺盛需求。在光纤制造中,四氯化锗扮演着“味精”般的关键角色。它是光纤预制棒纤芯掺杂的核心原料,主要作用是提高纤芯折射率等,让光纤的传输性能更“能打”。“在光纤预制棒的原材料成本里,锗的占比很低,但由于下游对锗材料的纯度要求高,加上国内锗供给较为集中、材料不可替代性强,相比其他材料,锗的供需矛盾会更为明显。”一家头部光纤预制棒生产商介绍。(上证报)
