Spherical tantalum powder is a metal element. The element corresponding to the element is steel gray metal, which has high corrosion resistance. It does not react to hydrochloric acid, concentrated nitric acid and aqua regia regardless of whether it is under cold or hot conditions.

Tantalum mainly exists in tantalite and co-exists with niobium. Spherical tantalum powder has moderate hardness and is rich in ductility, and can be drawn into thin filaments to make thin foils. Its thermal expansion coefficient is very small. Spherical tantalum powder has excellent chemical properties and high corrosion resistance. It can be used to make evaporators, etc., and can also be used as electrodes, rectifiers, and electrolytic capacitors for electron tubes. Medically used to make thin sheets or thin threads to repair damaged tissues. Although Spherical tantalum powder has strong corrosion resistance, its corrosion resistance is due to the formation of a stable tantalum pentoxide protective film on the surface.

Spherical tantalum powder application

1. Spherical tantalum powder is widely used in the fields of chemicals, electronics, military, machinery and aerospace to manufacture electronic components, heat-resistant materials, corrosion-resistant equipment, catalysts, molds, advanced optical glass, etc.;

2. In medicine, it is also used as a human body inspection object, surgical material and contrast agent;

3. Spherical tantalum powder is used in the most widely used capacitor products in the field of military electronics. The size of electronic products has become smaller and smaller, requiring Spherical tantalum powder capacitors to develop in the direction of miniaturization and high capacity;

4. By using micro-nano Spherical tantalum powder in the capacitor, a very thin insulating layer can be formed, thereby achieving high capacitance in a smaller size.
