preparation example Construction

[0045] The present invention also provides a method for preparing an anti-ultraviolet radiation transparent mid-wave infrared glass, comprising the following steps:

[0046] (1) raw material preparation: according to the mass fraction of glass composition, calculate the quality of corresponding each composition, weigh raw material; The specific composition and ratio of described raw material are as follows: BaO 2 11~23%; Ga 2 o 3 35-58%; CaO 2 20-43%; Y 2 o 3 10-26%; CeO 2 0.3-2.0%; if it is higher or lower than this range, it will cause defects such as glass crystallization, devitrification, reduced infrared transmission ability, and lack of anti-ultraviolet ability.

[0047] (2) Preparation: Grind all raw material components uniformly to form a mixture, put it into a platinum crucible, and place it in a silicon carbide rod electric furnace at 1100-1300 ° C for more than 8 hours, and obtain a uniform and free Glass liquid with bubbles; if the melting time is less t...

Abstract

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.

Description

technical field [0001] The invention relates to the field of optical glass materials, in particular to an anti-ultraviolet radiation-transmitting mid-wave infrared glass and a preparation method and application thereof. Background technique [0002] Infrared detection technology occupies a very important position in modern national defense high-tech. Guidance of various missiles, infrared early warning (including detection, identification and tracking, early warning satellites, early warning aircraft, various reconnaissance aircraft, etc.), observation and aiming (high energy beam interception weapons, etc.) are inseparable from infrared detection technology. Infrared materials are the basis of infrared photodetection technology, and play a pivotal role in the research of infrared technology. Infrared materials are mainly used as windows, hoods or fairings in infrared detectors and aircraft. The most important requirement for it is that it has as high a transmittance as pos...
