Tantalum Powder, Tantalum Metal Powder, 7440-25-7

Product Overview

Tantalum Powder is a rare, high-purity metallic powder derived from tantalum (chemical symbol: Ta, CAS No. 7440-25-7). It is valued for its extremely high melting point (3017°C), excellent corrosion resistance, superior electrical conductivity, and biocompatibility. These properties make it indispensable in advanced industries such as electronics, metallurgy, chemical processing, aerospace, medical applications, and additive manufacturing (3D printing).
