Pure Tantalum Sheet

Tantalum is a hard blue-gray rare transition metal with high ductility, thermal and electrical conductivity, and excellent corrosion resistance to acid. Tantalum is a refractory metal and is often used as a minor component of the alloy. The low chemical activity makes it suitable to replace platinum as an experimental material.

The characteristics of tantalum make its application field very broad. In the equipment for producing various inorganic acids, tantalum can be used to replace stainless steel, and its life span can be increased by several tens of times compared with stainless steel. In addition, in chemical, electronic, electrical, and other industries, tantalum can replace the precious metal platinum in the past, which greatly reduces the cost.

 

In addition, tantalum is also an important element for refining super-strength steel, corrosion-resistant steel, and heat-resistant steel alloys, and can provide special materials necessary for space technology such as rockets, spacecraft, and jet aircraft. The non-magnetic alloy made of tantalum and tungsten is widely used in the electrical industry, especially the carbide button composed of tantalum and carbon, which has great hardness and is comparable to diamond under high conditions. The turning tool made with it can cut harder alloys at high speed; various drill bits made with it can replace the hardest alloy or diamond. Therefore, tantalum is also regarded as the "vitamin" in the treatment and refining.

 

In modern medicine, tantalum can also play an important role. Studies have shown that tantalum not only does no harm to the human body but also the muscles of the human body can grow on it, which is called biocompatibility in medicine. Doctors use this property of tantalum to repair and seal the cracks and defects of the broken skull and limbs of the human body. At the same time, tantalum can be made into filaments one-tenth thinner than hair, used as sutures for visceral surgery, or embedded in artificial eyeballs.
