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.
Since niobium and tantalum have similar properties, as functional and structural materials, they have common application fields or can replace each other in most cases. But in fact, due to the different resources and properties, the main application fields and usage vary greatly. Niobium resources are abundant, with large output and consumption; tantalum resources are scarce, and output and consumption are small. The following are the main application areas of tantalum and niobium:
1. Electronics industry: The dense oxide film formed on the surface of tantalum metal has the unidirectional conductivity of valve metal, which is suitable for making capacitors with high reliability and long life. It is widely used in military equipment such as missiles, radars, televisions, electronic computers, and mobile phones. and high-tech fields.
2. Steel industry: 85% to 90% of niobium in the world is used in steel production in the form of ferroniobium. It is the leading microalloying element for niobium steel. As an alloying element, niobium is widely used in oil transportation, natural gas pipelines, automobile industry, shipbuilding, rail transportation, construction industry, heavy machinery and port construction.
3. Atomic energy industry: Niobium has the advantages of high melting point, corrosion resistance, and relatively small thermal neutron capture cross-section. It is suitable for cladding tubes and superheaters for uranium heating elements in reactors.
4. Petroleum and chemical industry: Niobium and tantalum have high corrosion resistance, good strength and processing plasticity, and are excellent structural materials for chemical equipment.
5. Aerospace industry: Niobium-tantalum heat-strength alloy has good thermal strength, heat resistance and processing performance, and is widely used in the manufacture of aerospace engine parts and gas turbine blades.
6. Cemented carbide: Tantalum carbide is an important additive of cemented carbide, its hardness is second only to diamond. Tantalum carbide is widely used in mechanical processing, automobile industry, petroleum geological drilling tools, etc.
seven. Superconducting materials: Some niobium alloys and compounds have very high superconducting transition temperatures, and are used to manufacture various industrial superconductors, such as superconducting generators, high-power magnets for accelerators, superconducting magnetic energy storage devices, and nuclear magnetic resonance imaging equipment.
eight. Medical field: Tantalum niobium has good biocompatibility and physiological corrosion resistance. Medical tantalum and niobium are used in the manufacture of bone plates, skull plate screws, implant roots, surgical instruments, etc.

About Tantalum metal.
Melting Point: 2996°C
Density: 16.6 g/cm3
Product range:Pure tantalum&Tantalum tungsten alloy
Tantalum is dark, dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity.
It has a melting point exceeded only by tungsten and rhenium.
As a high melting point metal, tantalum possesses a low vapour pressure and good electrical and thermal conductivity up to very high temperature.
The advantages of Ta are excellent corrosion resistance, high high-temperature strength, good machinability and good biocompatibility.
Features:Tantalum belong to the high melting point ,high boiling point rare metal color ,steel ,ductility and corrosion resistance
