Abstract—
Cooling of a melt with the composition Bi2O3·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°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.
