MSE PRO™ 3N5 (99.95%) Tantalum (Ta) Pellets Evaporation Materials

Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys. Due to their high stiffness and corrosion resistance, thin Tantalum films are used in electronic devices and x-ray optics. Using Tantalum films as superconductors is also under investigation.

The dimensions and purities can be customized upon request. Please contact us for customization or bulk orders
