Application of titanium nitride
Titanium nitride has excellent physical and chemical properties such as high melting point, good chemical stability, high hardness, and good electrical, thermal, and optical properties, making it very important in various fields, especially in the fields of new metal ceramics and gold substitute decoration. The demand for titanium nitride powder in industry is increasing. As a coating, titanium nitride is both inexpensive and wear-resistant, with many of its properties superior to vacuum coatings. The application prospects of titanium nitride are very broad.
It is mainly applied in the following areas:
(1) Titanium nitride has high biocompatibility and can be applied in clinical medicine and dentistry.

(5) Titanium nitride is a new type of multifunctional ceramic material. Adding a certain amount of titanium nitride to TiC Mo Ni series metal ceramics can significantly refine the hard phase grains, thereby improving the physical properties of the ceramics to a large extent both at room temperature and high temperature, and thus greatly enhancing the high-temperature corrosion resistance and oxidation resistance of the metal ceramics; Adding TiN powder in a certain proportion to ceramics can enhance their strength, toughness, and hardness; By adding nano titanium nitride to TiN/Al2O3 composite nano ceramics and mixing them evenly through various methods such as mechanical mixing, a conductive network is formed inside the ceramic material containing nano titanium nitride particles. This material can be used as an electronic component in the semiconductor industry.
(6) Adding a certain amount of TiN to magnesia carbon bricks can greatly improve their slag erosion resistance.
(7) Titanium nitride is an excellent structural material that can be used for jet propulsion and rockets. Titanium nitride alloys are also commonly used in the fields of bearings and sealing rings, highlighting the excellent application effects of titanium nitride.
