The effect of homogenization temperature and the melt cooling rate on the processes of non-isothermal crystallization of glassy Se and on the nature of phases formed in its matrix is revealed. The characteristic temperatures of thermal effects and activation energy of crystallization Ec are determined. As shown, the Ес value is determined by the polymerization index of Sen molecules, the concentrations of Sе8 molecules, pairs with the variable valence, and chain molecules in the trans-configuration positions. Crystallization of selenium amor-phous films is accompanied by a sharp decrease of their trans-mission. As revealed, the size of crystalline inclusions and the value of optical transmission are determined by the tem-perature and time annealing modes.
