Surface Tensions and Densities of Molten Al2O3 and Ti2O3

Surface Tensions and Densities of Molten Al2O3 and Ti2O3

Surface tensions and densities of molten Al2O3 and Ti2O3 were determined under Ar + 10% H2 gas by using the maximum bubble pressure method. Surface tension and density of molten Al2O3 near the melting point are 606 ± 6 mN/m and 3.06 ± 0.03 × 103 kg/m3, and those of molten Ti2O3 are 584 ± 5 mN/m and...

Zusammenfassung:Surface tensions and densities of molten Al2O3 and Ti2O3 were determined under Ar + 10% H2 gas by using the maximum bubble pressure method. Surface tension and density of molten Al2O3 near the melting point are 606 ± 6 mN/m and 3.06 ± 0.03 × 103 kg/m3, and those of molten Ti2O3 are 584 ± 5 mN/m and 3.91 ± 0.03 × 103 kg/m3, respectively. The results are compared with those of other moltem pure oxides having high melting points and discussed.
