Description

technical field [0001] The invention belongs to the technical field of special glass, and relates to an anti-ultraviolet absorption space radiation-resistant glass and a manufacturing process thereof. Background technique [0002] Deep space exploration usually refers to the exploration of the moon and space beyond the moon. The deep-space radiation environment is a major factor affecting deep-space exploration missions. It mainly includes solar particle events, galactic cosmic rays, captured radiation belts, and sunspot surface radiation. These high-energy electrons radiate to the surface of objects, destroying the crystal structure of surface materials and thus cause defects. High-energy protons and heavy ions can produce both ionization and displacement, which will cause the glass material on the spacecraft to become black and dark after being irradiated by particles, reduce the output power of solar cells, and degrade or even completely damage various semiconductor devi...
