Research has found that. Tantalum is virtually imperturbable to erosion and has been used as a surgical replacement for bone (e.g. skull). Making foil or silk thread can connect broken nerves; Use of tantalum: tantalum is a light gray metal with a slightly blue color. It has a wide range of applications due to its many exotic properties. Therefore, it is known as the "kingdom of metals" generalist.
Tantalum is very hard, with a hardness of -6. 5. It has a melting point of 2,996 degrees Celsius, the third-highest temperature in the world after tungsten and rhenium.
Tantalum is malleable and can be drawn into fine wires or thin foil. Its thermal expansion coefficient is very small, expanding by only 6.6 parts per million for every 1 degree Celsius rise. On top of that, it's very tough, even better than copper.
Tantalum is also an important element in the development of steel-making, corrosion-resistant steel and heat-resistant steel alloys, and can provide special materials needed for the development of space technologies such as rockets, spacecraft and jet aircraft. Non-magnetic alloys made of tantalum and tungsten are widely used in the electrical industry, especially tantalum carbide, which is composed of tantalum and carbon. Tantalum carbide has high hardness and is comparable to diamond even at high temperatures.
Turning tool made of it, can high-speed cutting a lot of hard alloy; It can be used to make a variety of drills, can replace * hard alloy or diamond. Therefore, tantalum is also considered as a "vitamin" in smelting. Tantalum also plays an important role in modern medicine. Studies have shown that tantalum not only does no harm to human body, but also human muscles can grow on it.
Doctors use this property to repair and seal fractures and defects in the body's broken skulls and limbs. Tantalum can also be made into filaments one-tenth thinner than a human hair, used as stitches in visceral surgery, or embedded in artificial eyeballs. It can even replace tendons and nerve fibers. Doctors use tantalum boards to make artificial ears, which are mounted on the head and then grafted onto the skin from the legs. After a period of time, the newly transplanted skin grows so well that it can hardly be seen as an artificial tantalum ear.
