Effect of temperature on radiation resistance of TiO2 powders during heating and modification by SiO2 nanoparticles

The temperature effect of 150 °С, 400 °С, and 800 °С on the phase composition, on variation in diffuse reflection spectra, and on the absorption coefficient of titanium dioxide powder during heating and modification by silicon dioxide nanoparticles (before and after irradiation with accelerated electrons) has been studied. The maximum value of the radiation resistance has been reached at the temperature of 800 °С.
