Titanium nitride (TiN) is an extremely hard material that is used as coating material for various tools and implants (TiN coating). It is also used in plastics such as PET flasks to improve the physical properties of these flasks and to improve the efficiency of PET manufacturing processes.


How can I come into contact with this material?

water bottlewater bottleIt is generally assumed that no titanium nitride nanoparticles are being released from the various applications since the nanomaterial is always used in a bound form within the product, e.g. in coatings or plastic products.


Is there any risk from this material to humans and the environment?

So far the potential negative effects of titanium nitride nanoparticles have been scarcely investigated. But the expert opinion today is that the use of titanium nitride in very thin layers (10 – 100 nm) on joint implants does not shown any harmful effect to human cells and thus is well-tolerated by the recipient of such prosthetic implants. However, whether titanium nitride nanoparticles could pose a danger to the environment has not been studied sufficiently to provide complete understanding here.



In everyday life, humans and the environment are exposed to very low levels of titanium nitride nanoparticles. Titanium nitride is considered to be non-toxic and therefore used as coating material for prosthetic implants


By the way...

  • Titanium nitride is a synthetic product that does not occur naturally.
  • No negative effects have been found upon dermal contact with titanium nitride particles.
