Abstract:

The paper presents some results of the research on the effect of UV irradiation on optical properties of materials (sodium and potassium silicates) for thermoregulating coatings (TRC) obtained from various rocks (diatomite, perlite) by hydrothermal-microwave synthesis. It is shown that UV radiation contributes to redistribution of the absorption intensity peaks responsible for defect formation in the crystal lattice. Absorption measurements of obtained materials for TRC irradiated at low temperature (-100°C)have shown that the intensity of silicate bond oscillations decreases because of the amplitude decrease due to "freezing" (in this case, the structure of spectra is preserved). When irradiated at high temperature (150°C) the picture is changed due to the fact that under UV irradiation, a "radiation annealing" takes place that contributes to stability of certain structural disorders.
