摘要 |
The present invention relates to a coated article including a coating supported by a glass substrate. The coating comprises from the glass substrate outwardly a first dielectric layer comprising silicon zirconium nitride or niobium oxide; a contact layer comprising at least one of NiCr, NiCrO x and NiCrN x ; a first IR reflecting layer comprising Ag; a second dielectric layer comprising the same material as the first dielectric layer; a third dielectric layer having an index of refraction n less than an index of refraction of at least one of the first and second dielectric layers; a contact layer comprising at least one of NiCr, NiCrO x and NiCrN x ; a second IR reflecting layer comprising Ag; a fourth dielectric layer comprising silicon oxide in case of niobium oxide as first dielectric layer or at least one of tin oxide and silicon nitride in case of silicon Zirconium nitride as first dielectric layer. Thereby, the article receives a visible transmission of at least 70% and a sheet resistance (R s ) of no greater than 10 ohms/square. |
