A comparative study of the radiation resistance of the optical properties of binders for spacecraft thermostatic housings was carried out: widely sold liquid glass K2SiO3 and newly developed liquid glass Li2SiO3. At the analisis of diffuse reflection spectra (ρλ) in the wavelenght range 0.2–2.5 μm and the integral radiation absorption coefficient (аs) both before and after electron radiation, an incomparably higher radiation resistance of Li2SiO3 liquid glass compared to K2SiO3 glass was established. The values of the change in the absorption coefficient ∆аs of liquid glass Li2SiO3 comparing to one of K2SiO3 liquid glass are several times less: for electron radiation with an estimate of 30 keV at a fluence Ф = 2 × 1016 cm–2 – 35 times; at Ф = 4 × 1016 cm–2 – 25 times; at Ф = 6 × 1016 cm–2 – 7 times. Analysis of of the factors that determine the radiation resistance of these glasses was made. The advantage in the radiation resistance of Li2SiO3 liquid glass is making it prospective for use as connecting compounds in thermal control coatings of spacecraft, in paints, ceramics and other areas of technology and industry with the presence of ionizing traces.
