Document Type and Number:
WIPO Patent Application WO/2024/084748
Kind Code:
A1
Abstract:
[Problem] To provide a radio wave transmission-type heat-shielding multilayer glass which has high visible light transmittance, excellent solar radiation shielding performance, and ultraviolet shielding performance, and which transmits radio waves in a millimeter wave band (28 GHz band) and a Sub6 band (4.5 GHz frequency band and 3.7 GHz frequency band) used in a 5th-generation mobile communication system. [Solution] A mixed coating film of composite tungsten oxide fine particles represented by a general formula, MxWOy, and antimony-doped tin oxide (SnO2:Sb) fine particles is formed on an air layer side of one sheet glass constituting a multilayer glass, wherein: the ratio of the antimony-doped tin oxide (SnO2:Sb) to the MxWOy is 5-20 wt%; the molar ratio x of the metal M to the tungsten W is in a range of 0.8-1.1; and the metal M contains at least aluminum (Al), tin (Sn), and zinc (Zn).
