Spherical tungsten powder is a type of tungsten powder that has been shaped into small spheres through a process known as atomization. In this process, molten tungsten is forced through a nozzle and then rapidly cooled with a gas or liquid. The resulting powder particles solidify into spherical shapes, which have a uniform size and smooth surface.

Spherical tungsten powder is commonly used in a variety of applications, including:

1. Additive manufacturing: Spherical tungsten powder is used in the production of tungsten parts through processes such as powder bed fusion and binder jetting.

2. Thermal spray coatings: Spherical tungsten powder is used as a feedstock material in thermal spray processes to produce coatings that are wear and corrosion-resistant.

3. Metal injection molding (MIM): Spherical tungsten powder is used as a feedstock material in MIM processes to produce tungsten parts with complex shapes and high density.

4. Electronics: Spherical tungsten powder is used in the production of electrical contacts, filaments, and other electronic components.

Spherical tungsten powder is prized for its high purity, uniform particle size, and excellent flowability, which make it well-suited for many high-performance applications.
