Application of Tantalum metal powder

The dense oxide film produced on the surface of tantalum powder has the properties of single-phase conductive valve metal, high resistivity, high dielectric constant, earthquake resistance, and long service life. It has important applications in high-tech fields such as electronics, metallurgy, steel, chemical engineering, hard alloys, atomic energy, superconducting technology, automotive electronics, aerospace, medical and health, and scientific research.

Advantages of Tantalum metal powder

1. High sphericity

2. Few satellite balls in the powder

3. Good flowability 4. Controllable particle size distribution of the powder

5. Almost no hollow powder

6. High loose density and tap density

7. Controllable chemical composition and low oxygen content
