Problems solved by technology

[0004] Looking at the high light transmittance glass technologies of various foreign companies, in the 1.5-2mm thick soda lime glass, the visible light 400-760nm transmittance (LTA) is limited to 90-92%, and the 800-1250nm red heat The near-infrared transmittance (TSIRA) is limited to 80-91%. Due to the poor transmittance of the red-hot near-infrared (TSIRA), the heat absorption of the glass is large, so that the temperature of the glass substrate is between 45-60°C. The change between them reduces the photoelectric conversion efficiency; more importantly, the Fe in the soda lime glass base material 2 o 3 The content requirements are very strict, all required to be between 0.01-0.03%, which greatly increases the manufacturing cost and process difficulty

Abstract

The invention discloses high-transmittance and high-infrared-penetration functional silicate glass, and belongs to the field of functional glass materials. The functional glass takes total weight of the functional silicate glass as a reference and comprises, in weight percent, 60-73% of SiO2, 5-17% of Na2O, 3-12% of CaO, 0.1-10% of Al2O3, 0.01-1% of MgO, 0.01-1% of K2O, 0.001-0.1% OF Fe2O3, 0.05-1% of CeO2 and 0.01-0.55 of B2O3. The invention further discloses a preparation method and an application of the functional glass materials. According to the glass, glass materials are greatly reduced,and the functional silicate glass with good transmittance and infrared penetration can be unexpectedly acquired by the aid of raw materials and a proportion.
