1. the window glass of one group of thin layer is coated with by evaporating deposition technique, this evaporating deposition technique is sputtering, this group thin layer gives its infrared reflection performance, keep the high-transmission rate of visible-range simultaneously, the performance in its middle level does not obviously change in the thermal treatment of this window glass through bending/quenching type, and this group thin layer comprises one or more layers layer based on silver and dielectric layer, wherein at least one deck is the layer of titanium oxide based on TiMOx or TiMOxNy type or titanium oxynitrides based at least one deck dielectric layer below the layer of silver, wherein M is one or more metals or silicon, the remarkable transformation of the crystalline structure of the layer based on titanium oxide that the atomic ratio of this metal or silicon deposits before being enough to prevent under thermal processes act,The metal comprised in component wherein based on the layer of titanium oxide or titanium oxynitrides belongs to the group be made up of Zr, Nb, Hf, Ta, Nd, V, Ce, W, Mo, La, Y, Al, wherein be not less than 10% based on the atomic ratio M/Ti of metal or silicon and titanium in the layer of titanium oxide or titanium oxynitridesDescribed window glass comprises one group of following layer:

  • glass/TiMOx or TiMOxNy/ZnO or ZnAlOz or ZnSnOz or ZnMgOz/Ag/ barrier/dielectric II.
