[en] Kinetics of the electron radiolysis products accumulations in alkali halide crystals after electron irradiation (3.5 MeV, 0.45 Mradxsec^-1) in the absorbed dose interval from 10² up to 5x10⁴ Mrad at high temperatures (400 up to 1000 K) has been studied. The investigation methods comprise optical spectroscopy, electron microscopy, chemical analysis of crystal dissolution products electron microdiffraction, measurement of stored energy. It shown that colloid particles distribution with respect to particle size i s widened with absorbed dose increasing and its maximum is shifted to larger particles. But at higher temperature of irradiation (870 K) the distributions cease to depend on irradiation dose absorbed and are fully determined by the irradiation temperature. The analysis of the temperature dependence of the colloid formation process in NaCl crystal allows one to outline three stages of the process: the first stage up to 520 K is characterized by intensive coagulation (the increase of colloidal particles number and size); thermal distruction of alkaline metal colloidal particles and chemical transformations of them into alkaline metal oxide colloidal particles are characteristic of the second stage (520 up to 670 K); at the third stage the next increase of colloidal particles concentration due to oxidation process is observed. It is shown also that the dose rate increase in several times leads to a considerable increase in colloidal metal yield
