Tantalum plate is a plate made of metal tantalum, which is a silver-white, high-density, corrosion-resistant, high-melting transition metal. It has the chemical symbol Ta, atomic number 73, and an atomic weight of 180.95. Tantalum is also a highly corrosion and high-temperature-resistant material with chemical stability and excellent electrical and thermal properties. It is a gray-black metal with a density as high as 16.6 g/cm^3 and a melting point as high as 3,017°C. Due to its excellent chemical stability and electrolyte chemistry, Tantalum is widely used in the manufacture of chemical reactors, vacuum furnaces, medical devices, capacitors, LEDs, and semiconductor devices. It is also often considered a strategic material due to its scarcity and high price. Its chemical composition only contains Ta element, no other impurities.
Tantalum sheet is a high-purity metallic material with the following physical and chemical properties:
1. Physical properties
- Density: 16.6 g/cm3
- Melting point: 3017°C
- Thermal conductivity: 57 W/(m·K)
- Coefficient of thermal expansion: 6.3×10-6/K
2. Chemical properties
Corrosion resistance: It has excellent corrosion resistance in most acids, alkalis, and salt solutions, especially for strong acid and strong alkali solutions such as hydrofluoric acid, sulfuric acid, hydrochloric acid, ammonium chloride and sodium hydroxide corrosion resistance.
Chemical stability: It has high chemical stability and is not prone to chemical reactions under high temperatures and high pressure.
