Modeling of the Bi2O3•SiO2 Melt Cooling Process and the Products of Melt Solidification under Various Conditions

Cooling of a melt with the composition Bi2O3 center dot SiO2 and the metastable phase Bi2SiO5 under various conditions has been studied by computer simulation with ProCAST software. Using previously reported thermophysical characteristics (thermal conductivity, heat capacity, and density) of the melt and metastable phase and the experimentally determined thermal diffusivity of the metastable Bi2SiO5 compound in the range 299-700 degrees C, we have evaluated the cooling rate, which has been shown to agree well with the experimentally determined one, confirming that the assumptions made in our simulations are quite adequate.

Automated summary

This study investigates the cooling process of a melt with the composition Bi2O3·SiO2 and the metastable phase Bi2SiO5 using computer simulation with ProCAST software. The calculated cooling rate is found to be in good agreement with experimental data, confirming the validity of the assumptions made in our simulations.
