Tantalum sheet definition and physical properties
Tantalum sheet is a thin sheet material made of metal tantalum (Ta) as the base material. Tantalum is a refractory metal with an atomic number of 73 and a melting point of up to 3017°C. It has excellent corrosion resistance and chemical stability. Pure tantalum sheets usually contain ≥99.95% tantalum, and some alloy tantalum sheets may add elements such as niobium (Nb) to improve performance.
Physical properties
Density: 16.6 g/cm³ (high-density material)
Hardness: Mohs hardness 6.5 (harder)
Conductivity: Resistivity 13.5 μΩ·cm (low resistance, suitable for electronic applications)
Coefficient of thermal expansion: 6.5×10⁻⁶/°C (similar to silicon, matching semiconductor technology)
