Resilience in the tantalum supply chain ScienceDirect
网页2018年2月1日 We aimed to analyze several resilience-promoting mechanisms such as: (a) diversity of supply, (b) material substitution, (c) recycling and (d) stockpiling. In the past decades, the tantalum market has experienced disruptions and significant price swings, which imply problems with its supply chain resilience and stability.
