Introduction and physical and chemical properties of tantalum wire
What is tantalum wire?
Tantalum wire is a thin wire made of tantalum metal material. Tantalum is a metal material with a high melting point, high corrosion resistance and good deformation ability. It has a high density, hardness comparable to metal castings, and high chemical and thermal stability.
Physical and chemical properties of tantalum wire
1. Physical properties
(1) Density: 16.65 g/cm³
(2) Melting point: 2996 ℃
(3) Thermal expansion coefficient: 6.4 × 10^-6 (20-100 ℃)
(4) Resistivity: 12.5 nΩ·m (20 ℃)
2. Chemical properties
Tantalum reacts very slowly with oxides, fluorides, chlorides and some oxidizing acids. In air, tantalum has good oxidation resistance.
