Definition of parameters of equation Fogel-Fulcher-Tamman for temperature dependence of viscosity in the field of transition a fluid-glass

Department of Physical Problems of the Buryat Scientific Center of the Siberian Branch of the RAS, Ulan-Ude For multicomponent optical glasses parametres of equation Fogel-Fulcher-Tamman in the field of a glass transition are spotted. On their bottom the share fluctuation the volume, frozen is calculated at temperature of transition a fluid-glass. It appears practically a constant at all explored glasses.
