Titanium Nitride Nanopowders Used on New Energy Saving Glass Coating

Titanium nitride nanopowders as coating, coating on the glass, TiN film thickness was prepared by 500 nm, having a NaCl type face-centered cubic structure and exhibits a preferred orientation (200) crystal face, a uniform grain size distribution of the film. Transmittance in the visible areais 60%, reflectivity is less than 10%.In the near-infrared light reflectivity is more than 40% TiN thin film resistor is 34.5 Ω, in accordance with the Drude theory can be calculated far infrared reflectance of the film of 71.5%, prepared as described in the TiN film to ensure sufficient light extraction conditions showed a good energy saving performance.

In order to seek more effective, easier to produce energy coated glass, the nano-scale TiN powder dispersed in the coating system, the formation of TiN thin film coatings used for energy-saving glass. The following reasons:

1, the small size of nano titanium nitride, which is easily dispersed in the coating;

2, nano-TiN coated with a uniform film coating is easy;

3, TiN film having a low resistivity, should have low emissivity properties

4, TiN film having a high visible light transmittance, can be guaranteed as a window function

5, TiN films in the near infrared region also has some reflectivity, this part of the energy also has an insulating effect, can be used as low-emissivity film than the film having a wider energy range of energy-efficient energy
