Title:
METHOD OF MANUFACTURING NEAR INFRARED RAY ABSORBING GLASS
Document Type and Number:
WIPO Patent Application WO/2019/171851
Kind Code:
A1
Abstract:
Provided is a method which facilitates the manufacturing of near infrared ray absorbing glass that has excellent spectral characteristics. The method of manufacturing near infrared ray absorbing glass that comprises, in mass%, 10 to 70% of P2O5, 3 to 40% of CuO, and over 0 to 50% of R2O (where R is at least one selected from Li, Na, and K) is characterized by heating and melting a raw material into molten glass, and bubbling oxidized gas into the molten glass while keeping the molten glass at a temperature of 1000°C or less.
