Abstract
The nature of attack of V2O5 melts on polycrystalline alumina and fused silica rods was studied under conditions of forced convection dissolution at several temperatures in the range 800°–1000°C. The rate of corrosion as a function of the square root of angular velocity of rotation at various temperatures was found to be linear. This was in agreement with the theoretical model of forced convection dissolution. Using the experimental data, the effective diffusivities were calculated for both silica and alumina. Throughout the temperature range of the present investigation, alumina was found to have greater diffusivity. As the dissolution was diffusion-controlled, it was concluded that silica would act as a better refractory than alumina in vanadium-rich environments.Keywords
