Mass transfer coefficients for the growth and the dissolution of potassium alum and sodium thiosulfate in a laboratory‐scale fluidized‐bed apparatus were determined and correlated in a form of the Frössling equation. The surface reaction rate for potassium alum was found to be dependent onthe crystal size.
