For the crystal growth of an oxide, a global analysis of heat transfer in the inductively heated Czochralski furnace was carried out, taking the radiative heat transfer within the crystal and the melt into account. As a result, the flow and temperature fields are strongly affected by the variation in optical properties of the crystal and the melt, and the melt-crystal interface shape becomes more convex to the melt as the optical absorption coefficients of both the crystal and the melt decrease.
