The physical properties of oxide melts such as silicate, aluminate, and borate are of importance not only to the extractin metallurgist as slags but also glass technologist. Recently, theese properties have been important in the production dof solid ionics materials from oxide melts. Numerous physical properties of oxide melts such as density, viscosity, electric conductivity, diffusivity and thermal conductivity have bean reported on the oxide melts, mainly those of silicate melts. However the values obtained from different studies are not in agreement, the reason being mainly the difliculty of measureing at high temperature. Some models have been constracted of the structure of oxide melts such as silicates and borates with reference to the physrcal propertres of oxide melts and X ray diffractron measurements, infrared spectroscopic studies, and Raman spectroscopic studies for quenched glassy samples.
