The invention discloses anti-ultraviolet radiation medium-wave infrared transmitting glass as well as a preparation method and application thereof. The anti-ultraviolet radiation medium-wave infrared transmitting glass comprises the following components in parts by mass: 11-23% of BaO2; 35 to 58% of Ga2O3; 20 to 43 percent of CaO2; 10 to 26 percent of Y2O3; and 0.3 to 2.0 percent of CeO2. According to the prepared anti-ultraviolet radiation medium-wave infrared transmitting glass, the visible light transmittance reduction under strong ultraviolet radiation is smaller than 2% and is far lower than the transmittance reduction (larger than 30%) of gallate glass under the same condition, the infrared transmitting performance is excellent (the infrared cut-off wavelength is 5600 nm, and the average transmittance of the infrared band is 88%), the heat shock resistance temperature difference is larger than 210 DEG C, and the anti-ultraviolet radiation medium-wave infrared transmitting glass is suitable for being used in the field of glass. And the acid-resistant stability is grade 1, and good physical and chemical stability is achieved.
本发明公开了一种抗紫外辐射透中波红外玻璃及其制备方法和应用,含有以下质量份数的组分:BaO2 11~23%;Ga2O3 35~58%;CaO2 20~43%;Y2O3 10~26%;CeO2 0.3~2.0%。本发明所制备的抗紫外辐射透中波红外玻璃在强紫外线辐射下可见光透过率降低小于2%,远远低于镓酸盐玻璃在同等条件下透过率的降低(大于30%),且透红外性能优异(红外截止波长:5600nm,红外波段平均透过率:88%),耐热冲击温差大于210℃,耐酸稳定性为1级,具有良好的物理和化学稳定性。
