Density, viscosity and surface tension of melts in the system SiO₂-TiO₂-Al₂O₃ at 1600°C have been measured by means of the Archimedes' method with two spheres, the drawing sphere method and the Wilhelmy's method, respectively. The accuracies of these measurements were confirmed with the molten B₂O₃ in the temperature range from 400° to 1400°C. As the result, density and viscosity of the molten B₂O₃ approximately agreed with values of literatures, but surface tension was affected by viscosity of the melt. However, influence of viscosity of the melt on surface tension could be taken off by a modification of “intermittent lowering”. When the contents of Al₂O₃ in the system SiO₂-TiO₂-Al₂O₃ were in the range from the eutectic composition of the system SiO₂-TiO₂ (89.5wt% SiO₂, 10.5wt% TiO₂) up to about 12.5wt% Al₂O₃, all the values of density, viscosity and surface tension of the melts decreased with increase of Al₂O₃ content. Above 12.5wt% Al₂O₃, these values increased with increase of Al₂O₃ content because of the formation of mullite in the melt.
