Ultra low expansion microcrystalline glass refers to the glass composed of Li2O, Al2O3, and SiO2, which is formed with negative expansion after strict controlled crystallization treatment β- A composite material composed of quartz solid solution nanocrystalline phase and positively expanding glass phase, with excellent optical, thermal, mechanical and other properties, is currently the material with the best dimensional stability in variable temperature environments.
Ultra low expansion microcrystalline glass has the characteristics of integrating structure and function, mainly used for laser gyroscope resonant cavities, space camera reflector blanks, and large astronomical telescope mirrors.
