বিষয়ে Tantalum
Tantalum is a hard, blue-gray, lustrous metal that has the fourth-highest melting point. It is almost immune to chemical attack below 150 degrees C and is biocompatible.
Uses & Applications
Electronic capacitors (mobile phones, computers), surgical implants, jet engine components, and chemical equipment.
মজা কথা
Tantalum capacitors are in virtually every smartphone. Mining of coltan (tantalum ore) has been linked to conflict in the Congo.
