FIELD: chemistry.
SUBSTANCE: invention relates to thermally treated glass having a low-emission coating, which provides effective transmission in the visible range of the solar energy spectrum and at the same time effective reflection of radiation in the infrared and near-infrared ranges. Low-emissivity coating (101) of the thermally treated glass (10) comprises the following layers located outward from glass (10), respectively: first dielectric layer (201), second dielectric layer (202), first seed layer (211), second seed layer (212), first infrared radiation reflecting layer (22), first barrier layer (23), third dielectric layer (241), fourth dielectric layer (242), third seed layer (243), second infrared reflecting layer (25), second barrier layer (26), fifth dielectric layer (271), upper dielectric layer (272). First dielectric layer (201) is selected from SixNy, SiOxNy, ZnSnOx, TiOx, TiNx, ZrNx. Second dielectric layer (202) is selected from TiOx, ZrOx, NbOx. First seed layer (211) is selected from NiCr, NiCrOx, TiOx, ZnSnOx, ZnAlOx, ZnOx. Second seed layer (212) contains NiCr or NiCrOx, has thickness ranging from 0.3 nm to 1.2 nm. First barrier layer (23) is selected from NiCr, NiCrOx, Ti, TiOx, ZnAlOx, ZnOx. Third dielectric layer (241) is selected from SixNy, TiNx, ZrNx, ZnSnOx, ZnAlOx, SiAlNx, SiAlOxNy, SiOxNy, TiOx, ZnOx. Fourth dielectric layer (242) is selected from SixNy, TiNx, ZrNx, ZnSnOx, ZnAlOx, SiOxNy, TiOx, ZnOx. Third seed layer (243) is selected from NiCr, NiCrOx, TiOx, ZnSnOx, ZnAlOx, ZnOx. Second barrier layer (26) is selected from NiCr, NiCrOx, Ti, TiOx, ZnAlOx, ZnOx. Fifth dielectric layer (271) is selected from ZnSnOx, ZnAlOx, SiOxNy, ZrOx, SiOx, SixNy, TiOx, ZnOx. Upper dielectric layer (272) contains SiOxNy.
EFFECT: high efficiency of transmitting visible light and reflecting solar energy.
