What is high purity tantalum? What are the specifications and uses?

High purity tantalum refers to tantalum materials with a metal purity of 99.95% and above. Tantalum is a rare metal with stable chemical properties, high melting point, high density, high strength, good corrosion resistance, strong oxidation resistance, etc. It is an important structural and functional material. High purity tantalum is one of the highest purity tantalum materials, with extremely high chemical stability and physical properties, and is widely used in the following fields:

Semiconductor industry: High-purity tantalum is commonly used in the manufacture of various semiconductor devices, such as thermistors, field effect transistors (FETs), thin film transistors (TFTs), transistors (MOSFETs), and so on.

Medical devices: High-purity tantalum has good biocompatibility and can be used to manufacture artificial joints, stents, vascular patches and other medical devices.

Chemical industry: high purity tantalum has good corrosion resistance and can be used to manufacture chemical equipment, reactors, distillers, etc.

Vacuum technology: high-purity tantalum can withstand high-temperature and high-vacuum environments, and can be used in the manufacture of vacuum furnaces, vacuum tubes, vacuum valves and so on.

Aerospace industry: high purity tantalum has high strength and high temperature stability, and can be used to manufacture rocket engine parts, aero-engine blades and so on.

The specifications of high purity tantalum are usually divided according to the oxygen content, impurity content and other indicators. The production process of high-purity tantalum requires very strict process control, so the manufacturing cost is relatively high.
