Abstract
A thermal insulating glass includes a glass substrate and a thermal insulating layer. The thermal insulating layer includes composite tungsten oxide and a binder. The composite tungsten oxide is represented by formula (1): MxWO3-yAy (1), where M is an alkali metal element or an alkaline earth metal element, W is tungsten, O is oxygen, A is a halogen element, and 0<x≤1 and 0≤y≤0.5. And the binder includes one or more of the following components: silicon dioxide, titanium dioxide, and aluminium oxide. The thermal insulating glass can prevent the occurrence of obscuration. The thermal insulating has infrared reflectivity, high strength and good wear resistance, and can effectively resist high temperature and strong oxidation environment.
