Abstract

The present study shows the dependence of the temperature of glass transition — T g upon the presence and quantity of doping Pr atoms. Substantial effect of the form — chemical nature of compound from which the doping atoms are incorporated into the glass has been displayed as well. With the increase of the content of sulfidic form T g values approach the level of undoped glasses. Thus, if the studied glasses are doped by sulfidic form, bonded areas atoms of Pr so atoms of S. Glasses doped by halogenous source of Pr behave differently; the shift of the T g value does not change with the amount of the dopand, displaying the anion deficiency of glass stoichiometry in studied interval of halogenous dopands. Generally, a very slight non-stability of the glass against the oxidation in temperature region of glass transition is observed.
