Heat Treatment：
Tantalum exhibits high reactivity towards interstitials elements like Hydrogen, Nitrogen and Oxygen. Also it may react with Hydrocarbons. Its recrystallization temperature varies between 900 °C and 1450 °C. Vacuum and dry inert gases are most suitable as heat treatment atmospheres. The duration of the heat treatment may depend on the equipment, the process and the experience with the material. Lubricants should be completely removed prior to the heat treatment. If not, they may react with the Tantalum and cause embrittlement of the material.
Remark: Special requirements of tantalum wire will to be agreed on by the supplier and buyer of negotiations.

Tantalum wire is widely used in electronic industry. It is mainly used as anodic lead wire of tantalum electrolytic capacitor. Tantalum wire was the first material used for filaments in light bulbs. Tantalum wire is also used in the electronics industry in the manufacture of rectifiers and capacitors. Other applications include medical devices, chemical processing, and lighting applications. Whether in the cold and hot conditions, hydrochloric acid, concentrated nitric acid or in "aqua regia", tantalum wire has no chemical reaction. In medicine, tantalum is used to make flakes or sewing thread to mend the destructive tissue.
