Transport Phenomena In Oxidic Glass-Forming Melts

Viscosities, electrical conductivities and Seebeck-coefficients of a number of glass-forming oxidic melts are presented and discussed. The data support the notion that glass melts do have a residual, temperature-dependent structure that significantly determines mass, momentum and heat transport. It is shown that the use of Tg/T as reduced variable helps to develop a deeper insight in the underlying physics of these transport properties.
