耐高温透明材料的研究进展.

As an important window for photoelectric information transmission with the outside world under high temperature conditions, high temperature resistant transparent materials are mainly used in emerging fields such as spacecraft, missile, high-temperature and high-pressure container and laser. At present, high temperature resistant transparent materials mainly include high temperature resistant organic materials, crystal materials and tempered glass. Tempered glass is the most commonly used high-temperature resistant transparent material at present. Compared with chemical tempered glass, physical tempered glass has higher temperature resistance, but both have the problem of toughened stress attenuation at high temperature. Typical products of tempered glass include physical tempered alkali-free aluminosilicate glass and chemical tempered lithium aluminosilicate glass. Finally, the author looks forward to the development trend of high temperature resistant transparent materials. [ABSTRACT FROM AUTHOR]
