Nanoparticle research has become an area of interest to scientists due to the unexpected results produced by altering the atomic and molecular properties of elements. This article deals with the properties and applications of titanium nitride nanoparticles.
Titanium nitride (TiN) is available in coated, dispersed, high and ultra high purity forms. Their high hardness, high temperature chemical stability, high melting point, infrared absorption and UV shielding find a number of useful applications. Titanium belongs to Block D, Period 4 while nitrogen belongs to Block P, Period 2 of the periodic table. Some of the alternate names of titanium nitride are tinite, nitridotitanium and azanylidynetitanium. It is important to maintain dryness while storing these nanoparticles and also avoid any stress on them.
The following tables list the chemical properties of titanium nitride.

Titanium nitride nanoparticles appear in the form of a brown powder having a spherical surface area. The table below provides the physical properties of these nanoparticles.
The thermal properties of titanium nitride nanoparticles are as below.
Given below are some of the chief applications of titanium nitride.
- Making of plastic packaging materials like PET bottles
- In solar vacuum tube, due to high absorption of sunlight
- High temperature furnaces for energy consumption
- Making of artificial limbs, biological materials
- Making optical devices in harsh environments
- Used as alloy modificators in cemented carbides.
