About Tantalum

Tantalum is a highly corrosion-resistant refractory metal essential for miniaturized electronic capacitors found in smartphones, computers, and medical devices. The Democratic Republic of Congo and surrounding central African nations are major sources, and tantalum has been designated a conflict mineral subject to supply chain due diligence requirements. Its biocompatibility also makes it valuable for surgical implants.
