Medical applications of tantalum

Tantalum also plays an important role in surgical treatment. It can not only be used to make medical devices, but also be a good "biological adaptive material".

For example, tantalum can be used to repair skull injuries, tantalum wire can be used to sew nerves and tendons together, tantalum strips can be used to replace broken bones and joints, tantalum gauze or mesh made from tantalum wire can be used to repair muscle tissue...

In hospitals, there are cases where a broken bone in the human body is replaced with tantalum strips, and over a period of time, muscle actually grows on the tantalum strips, just as it does on the real bone. No wonder tantalum is called a "biophilic metal"

Why does tantalum have such a strange effect in surgery?

The key is because it has excellent corrosion resistance, not with a variety of liquid substances in the human body, and almost completely does not damage the organism tissue, can adapt to any sterilization methods, so it can be combined with organic tissue for a long time and harmless to stay in the human body.

In addition to such good use in surgery, niobium and tantalum can also be used to make electrolytic capacitors, rectifiers and so on, taking advantage of their mechanical stability.

In particular, more than half of tantalum is currently used to produce solid electrolytic capacitors with large capacity, small volume and high stability. Hundreds of millions of them are produced worldwide every year.

Tantalum electrolytic capacitors do not live up to people's high expectations, it has many advantages compared with other materials.

It than with the size of the other capacitor "brothers" of the five times larger capacitance, and very reliable, seismic, wide working temperature range, long service life and is now extensively used in electronic computers, radar, missile, supersonic aircraft, automatic control device, and color TV, stereo TV and other electronic circuits.
