Titanium nitride has a high superconducting critical temperature, the superconducting material is excellent. Particularly striking is that titanium nitride coating and sintered body has a satisfactory gold, can be used as vouchers decorative materials, has a good imitation gold effect, decorative value, and has anti-corrosion and prolong the life of crafts. Coated with a glass or a titanium nitride film, a new "hot mirror materials," when the film thickness is greater than 90nm, infrared reflectance greater than 75%, improving the thermal insulation properties of the glass.

Color titanium nitride film can also be adjusted, with the lower nitrogen content, the film will show a yellow, bronze, pink and other color, very beautiful. Currently, due to the development of nitrogen-containing metal nitride ceramic tools, leaving a sharp increase in the need for titanium powder together; and the international monetary equivalent decoration technology development is quite fast, titanium nitride applied in this area has very broad prospects. Not only because of the low price of titanium nitride coating, but also because of its performance in terms of resistance to corrosion, abrasion, etc. are better than vacuum coating. Therefore, the study of titanium nitride has important economic significance.
