A modified rotating-finger test (RFT) device was equipped with high-resolution laser to scan the sample surface for dimension measurement. Generally, refractory dissolution in molten slag is controlled by diffusion through a boundary layer and diffusivity is the most important parameter to quantify dissolution. The data obtained from modified RFT studies were applied to accurately determine effective binary diffusivity using simulation method or mass transfer equation.
