Solar control coating on glass

Abstract One of the various solar control glasses, a silver-based multilayer film formed by sputtering is becoming increasingly important because of its excellent and versatile performance. Recently major progress has been made in the sputtering process by several manufacturers, which has enabled both a stable and high rate of deposition. Efforts to improve the durability of sputter coating have been maintained seeking a flexible production process and expanded applications.

Zirconium silicon oxide films for durable solar control coatings

Abstract Zirconium silicon oxide films were deposited by dc reactive magnetron sputtering of Zrue5f8Si alloy targets. The character and durability of these films were investigated. Thin film X-ray diffraction analysis showed that the film structure changed from crystalline to amorphous with an abrupt decrease of internal stress for an SiO 2 content of more than 20 mol%. Reduction of friction due to the amorphous structure was related to an improved mechanical durability. Films with an SiO 2 content of 30–90 mol% were favorable as a durable protection layer. Taber abrasion of a double-layer system (amorphous Zrue5f8Si oxide/TiN x /glass) indicated that not only the reduction of friction but also the oxide thickness was a key factor for the improved mechanical resistance.
