SEMI-EMPIRICAL EQUATION OF VISCOSITY OF THREE- COMPONENT INORGANIC GLASSES

UDK: 539.213

Application of new equation to temperature dependence of viscosity of three- component glasses GeO2 – Na2O – PbO, GeO2 – Na2O – BeO, B2O3 – CaO – Al2O3, B2O3 – PbO – Al2O3 is considered. The equation is in satisfactory consent with experimental data, with rare exception. On the received values of empirical constants the energy of atom delocalization and the potential of kinetic unit jump in new condition were calculated.

silicate glasses, delocalization of bridging atom, viscous current, vitrification area, free energy of activation of fluidity.
