Tungsten acid can be applied for the manufacture of thermal insulating glass. Tungstic acid belongs to the category of inorganic absorbents and has similarity with inorganic absorbents. Comparison of Infrared Absorbers 1. Organic absorbents, such as synthetic dyes, cost less. But, it has the disadvantage of poor heat resistance and easy decomposition. 2. Inorganic absorbents, such as metal complexes, have the advantages of high reflectivity, safety, and high durability. While their prices are relatively high. When installed in the envelope…
