Tantalum is primarily found in tantalite, often in association with niobium. Tantalum has moderate hardness and is highly ductile. It possesses exceptional chemical properties, including extremely high corrosion resistance. Whether in cold or hot conditions, tantalum does not react with hydrochloric acid, concentrated nitric acid, or aqua regia. Although tantalum has strong corrosion resistance, this is due to the formation of a stable protective film of tantalum pentoxide (Ta2O5) on its surface.

Tantalum powder description
Tantalum powder is a fine, dark gray metallic powder that is produced from tantalum metal. It is highly resistant to corrosion and has a high melting point, making it suitable for various industrial applications. The powder particles are typically spherical or irregularly shaped, with an average particle size ranging from a few micrometers to several hundred micrometers.
Tantalum powder is known for its high density, which is around 16.6 grams per cubic centimeter. It has excellent thermal and electrical conductivity properties, making it useful in electronic components such as capacitors, resistors, and semiconductors. The powder is also widely used in the production of superalloys, which are high-performance materials used in aerospace, defense, and chemical industries.
Tantalum powder is a versatile material with various industrial applications, offering excellent corrosion resistance, high density, and good thermal and electrical conductivity properties.
