Density and Surface Tension of Bi₂SiO₅ Melts

Abstract:

Metastable crystal Bi₂SiO₅ has significant properties including dielectric, thermoelectricity and nonlinear optical properties. Metastable crystal Bi₂SiO₅ has been successfully prepared by melt cooling method in this study. Surface tension of high-temperature melt Bi₂SiO₅ was measured by Suspension method; metastable crystal Bi₂SiO₅ construction was assigned by IR(Infrared Radiation). The experimental result showed that Bi₂SiO₅ flux density decreased with the increasing temperature in 830-1095°C range; surface tension changed quadratic with the decreasing temperature. The [SiO₄]^4- anions of Bi₂SiO₅ originated from the isolated [SiO₄] tetrahedron in the glass to a chain connected structure.
