Tantalum Rod

Tantalum is a shiny, silvery colored metal which is heavy, dense, malleable and ductile when pure. It is found in small quantities in minerals (generally in conjunction with niobium).

Description
 

Tantalum is a shiny, silvery colored metal which is heavy, dense, malleable and ductile when pure. It is found in small quantities in minerals (generally in conjunction with niobium), and is isolated by conversion to the oxide and then the fluoro-complex, K2TaF7, from which the pure metal is obtained by electrolysis.

 

Tantalum is extremely corrosion resistant due to the formation of an oxide film, and is also resistant to acid attack (with the exception of HF).

It will react with fused alkalis and a variety of non-metals at elevated temperatures.
 

Tantalum rod, also known as tantalum bar, can be used as laboratory apparatus which has to have good corrosion resistance, and is also used within the chemical industry for similar reasons.

 

Advantages of Tantalum Rod
1. Excellent corrosion resistance
2. High temperature strength
3. Easy to machine
4. Good biocompatibility
