Spherical tantalum powder
Product Description
Spherical tantalum powder has a series of excellent properties such as high melting point, low vapor pressure, good cold working performance, high chemical stability, strong resistance to liquid metal corrosion, and large surface oxide film dielectric constant. It is used in electronics, metallurgy, steel , Chemical, cemented carbide, atomic energy, superconducting technology, automotive electronics, aerospace, medical and health, scientific research and other high-tech fields have important applications.
Main properties:Spherical tantalum powder has high purity (99.95%), small particle size (50nm), low oxygen content (<200ppm), good sphericity (>95%), fewer satellite balls, and good fluidity.

Product Features
This product should be stored in a cool, dry room to avoid heavy pressure. It should not be exposed to the air during use, so as to avoid moisture absorption and agglomeration, which will affect the dispersion performance and use effect. Unused products should be sealed or stored in a vacuum after unpacking.
