Titanium Nitride (TiN) Nanoparticles
Titanium nitride (TiN) nanoparticles are usually in a face-centered cubic crystalline structure. TiN nanoparticles show good thermal stability, wear and corrosion resistance, excellent hardness, and chemical inertness. In addition to these properties, TiN also provides the well-known metallic properties of Ti. The melting point of TiN nanoparticles is approximately 2950°C while the zeta potential is approximately -17 mV. Most importantly, TiN nanoparticles show intriguing optical properties. TiN exhibits plasmonic behavior similar to Ag and Au. The advantage of TiN over Au and Ag is its low cost and thermal stability. Owing to these properties TiN is considered as a promising alternative for plasmonic material and is known to exhibit localized surface plasmon resonances (LSPR) within the near-infrared (NIR) biological transparency window. The important application areas of TiN nanoparticles are listed as;
- Coating materials,
- Cermets (metallic ceramics),
- Cutting tools,
- Refractory materials,
- Electrodes of electrochemical capacitors,
- Plasmonic materials.
