Tantalum Metal Sheet
Application of tantalum metal sheet:
• Medically used to make thin sheets or threads to mend damaged tissue.
• Electrodes of electron tubes, rectifiers, electrolytic capacitors.
Product Introduction
1. Product name: Tantalum Metal Sheet
The melting point of tantalum is 2980℃, which is the third most refractory metal after tungsten and rhenium. Pure tantalum has a slightly blue color and excellent plasticity. It can be rolled into very thin (less than 0.01 mm) plates in cold state without intermediate annealing. Although the melting point and boiling point of tantalum are high, the electron work function is lower than that of refractory metals such as tungsten and molybdenum. Due to its weak ability to emit electrons, Tantalum metal sheet has been applied in electric vacuum technology.
