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.
